A Professional Air Flow Laboratory The A.R.I. air flow laboratory is unique (the only one of its kind in the region) and is designed for testing air valves. The air flow lab was designed and operates according to the ISO 17025 global standard and was adapted to meet the ISO 9001 quality standard and the ISO 14001 environmental standard. Bench test assessments are carried out according to worldwide testing standards as well as the European standard EN 1074. The initial calibration for the air flow lab was based on results from the CESAME (France) High Pressure Test Bench used for flow calibration and testing. This lab calibrates large diameter gas meters based on the principle of the ORIFICE PLATE.

The A.R.I. air flow laboratory performs assessments of air flow rates during intake and discharge, air flow tests for air valve premature closure as well as a vacuum bench test which tests the flow rate for air intake into air valves when the pipeline is under negative pressure. These tests are carried out and calculated in accordance with international standards for moisture and temperature variables.The air flow laboratory tests all types of air valves (air release, air & vacuum, combination, non-slam, one-way etc.) that operate on water and wastewater systems and are in the diameter range of 1/2” to 12”. The air flow laboratory employs 4 air storage tanks, each one with a volume capacity of 10 cubic meters, plus an additional 10 cubic meter air tank that is employed as the working tank.The air is stored at 13 bar of pressure and enables testing of air valves up to 12” in diameter and, with an additional compressor, enables automatic air valves to be tested at a pressure of 16 bars.

The air flow laboratory is computerized; therefore, once the characteristics of the tested air valves are entered in the computer and the air valve is connected to the test bench, the test is run. At its conclusion, the test reports are immediately available on the computer without further processing.The air flow lab is open to invited guests and trainees, who are able to view the testing and receive the results in real time, either viewed on a large screen or printed as a hard copy.

Air ValvesThe A.R.I. line of automatic air release valves and the automatic air release components of A.R.I. combination air valves are based on the rolling seal technology. The A.R.I. patented sealing mechanism replaces traditional configurations that incorporate a ball float closing against a round orifice. While the system is under pressure the A.R.I. rolling seal mechanism, with its aerodynamically-designed float, releases air in large quantities, often greater than in traditional valves. They also provide for the soft dynamic closure of the valve. This concept of a rolling seal mechanism enabled A.R.I. to develop small, lightweight, cost effective air valves.The self-cleaning feature of the rolling seal mechanism greatly reduces the possibility of clogging, leaking and the adhesion of suspended particles to the rolling seal surface. The valve body and interior components are made of corrosion-resistant materials. This ensures years of corrosion-free and maintenance-free operation, even under extreme environmental conditions.The A.R.I. line of products also includes a wide variety of air & vacuum and combination air valves. They are made of the same quality materials as the automatic air release valves and provide the same level of quality and assurances.These valves are offered in dimensions of 1/2” to 1” (automatic air release valves) and 1" to 12"(air & vacuum and combination air valves). They provide solutions for various applications in all industrial fields. These products are lightweight, have a compact profile and are offered at competitive prices.

Air in Liquid Transmission SystemThe quantity of free air must be controlled in liquid transmission systems. The presence of air/gas bubbles and pockets can be beneficial or detrimental to the transmission system under different conditions. The absence of air, such as exist under vacuum conditions, prevents suitable protection for the transmission systems.

Damage caused by the presence of air in the system1. Air blockage in the line causes unstable flow of the liquid and, in extreme circumstances, a total stoppage of flow.2. High head losses, resulting in large energy losses.3 The impact of surge, as a result of the presence of air in the system, can cause damage to pipes, accessories and connectors.4. Erroneous readings of water meters and automatic metering valves.5. Extensive damage to impeller systems in water meters, flow regulators, sprinklers and sprayers.6. Pitting and increased corrosion in metal components of the systems.7. Safety risks to operators increase due to the possibility of high energy bursts in locations where there are concentrations of compressed air.

Damage caused by the absence of air in the systemVacuum enhanced problems and damages:- Suction of mud and dirt through faulty connections, cracks in pipes and accessories, etc.- Suction of seals and gaskets, in–line fittings, and other internal accessories of pipes.- Uncontrolled suction of injected chemicals into the system.- Pipe or accessory collapse.- In some cases, the absence of an air cushion can increase the damages of surge and slam phenomena.

Innovative Valves for Liquid Transmission Applications

INTRODUCTION

Using A.R.I Air Valves to Control Air and Prevent DamageThere are three principal types of air valves used in liquid transmission applications:

Air & Vacuum ValvesAutomatic Air Release Valves Combination (double orifice) Air Valves

Air & Vacuum Valves automatically discharge air at high flow rates during filling of the system and admit air at high flow rates during draining, at water column separation, and in cases of down-surge in the system.Air & vacuum valves are known also as: large orifice air valves, vacuum breakers, low-pressure air valves and air vacuum valves.Automatic Air Release Valves release air entrapped in the system while under pressure. The air release flow rates of the automatic air release valves are lower than those of the air & vacuum valves. They are also known as: air release valves and small orifice air valves.Combination Air Valves include both air & vacuum and automatic air release components in one unit. They perform both functions:

- They discharge air at high flow rates during filling of the system and admit air at high flow rates at drainage or water column separation, AND - They release entrapped air while the system is under pressure.

Combination air valves are also known as double orifice air valves.

Installation and LocationIt is highly recommended that a basic review be made before selecting the appropriate air valves and determining their sizes and locations:- The chemical composition of the liquid that passes through them.- The possibility of extreme pressure changes such as up-surges and down-surges.- Analysis using ARIavCAD software for efficient design of the system (software available from A.R.I).

Typical installation locations:- In pump stations.- At locations where pressure drops.- At peaks along the line.- At locations of large convex slope changes- Along line segments without air valves.- Near isolating valves on the line.- On filter setups.- Before flow meters and automatic devices.- At line ends.

INTRODUCTION

Recommendations for the Determination of the Required Diameter of Air & Vacuum and Combination Air Valves To determine the diameter of air valve required, the first essential step is to define the task that the air valve must perform and the level of protection that the valve must provide. The principle tasks of an air valve are: 1 - The controlled or free discharge of air during the line filling stage:A. Controlled discharge – The air valve diameter is determined in order to limit flow / filling speed. B. Free discharge – The air valve is used to discharge air during line filling, but is not used to limit flow / filling speed. 2- Intake of air to prevent negative pressure (vacuum), down-surge and/or cavitation:A. When the line is drained through drainage valves with a defined location and size.B. When the line bursts at predefined or not defined points along its length; it's bursting up to a pre-determined size of burst in the pipe and the free drainage of water out of the line through the burst. C. When there is water column separation consequential to extreme changes in the regimen of water flow through the pipe. The required air flow rate and the air valve diameter are determined in accordance with the objective sought when installing the air valve and as explained below: - If the purpose of the air valve is only to limit filling speed – the required air release speed is equal to the filling rate (for the system), which is a function of the required filling rate. - If the purpose of the air valve is to protect the system in the event of an burst, which splits the pipe across its entire cross section, with consequential free flowing drainage of the line, the accepted method is to determine the required rate of air intake according to a burst analysis based on one of the flow equations, such as the Hazen – Williams equation:

Burst AnalysisThe burst analysis is based on the Hazen Williams Equation:

QB =KC H WD2 .63(h f / L ac t)0.54 and L ac t = (h f

2+L hp2) 0.5

Where, in our case:

QB = Air intake flow rate requirement for vacuum protection at full diameter pipe burst – m3/sec

K = Unit constant = 0.278 for metric units

C H W = Hazen Williams Coefficient for the pipen- no units

D = Diameter of pipe – m

h f = Elevation change between the two ends of the pipe segment being analyzed – m

L ac t = Actual length of the pipe segment (not its horizontal projection)- m

L hp = Length of the horizontal projection of the pipe segment - m

Given that the results of this analysis are often extreme, the common practice is to supply air at a percentage of the calculated results.A.R.I. does not recommend using the Burst Equation.- If the purpose of the air valve is to protect the system during drainage through a defined drainage valve or at pipe rupture, it is recommended to use the drainage and rupture analysis based on the orifice equation.

Drainage and Rupture AnalysesAir intake flow rate requirement at drainage through a drain valve or a rupture is:

1 . Q d = C d(πD d2/4)(2g Δh) 0.5

For drains or ruptures whose equivalent diameters are greater than 30% of the pipe diameter:

2 . Q d = MC d(πD d2/4)(2g Δh) 0.5 and M= {1/[1-(D d/D p) 4] }0 .5

Where:

Q d = Air intake flow rate requirement – m2/sec

C d = Orifice coefficient – 0.6 is a common default value

D d = Drain valve or rupture equivalent diameter - m

g = Gravitational acceleration – 9.81 m/sec2

Δh = Elevation difference between the air valve and the drain valve or rupture ‐ m

M = Correction factor

D p = Diameter of the pipe ‐ m

Here, the initial Qd was calculated with no losses. After the initial calculation of Qd , we calculate the Hazen Williams friction head loss, hf due to this initial Qd:

3 . h f = Q d1.852L act / (K 1.852C d

1.852D d4.87) and

L act = (Δh 12+L hp1

2) 0.5+ (Δh 22+L hp2

2) 0.5+… (Δh n2+L hpn

2) 0.5

Where:

h f = Hazen Williams friction head loss due to the initial Qd - m

K = unit constant = 0.278 for metric units

L act = Actual total pipe length between the air valve and the drain or rupture – m

Δh 1, Δh 2,… Δh n = Elevation change of each of the pipe segments between the air valve and the drain or rupture - m

L hp1, L hp2, … L hpn = Length of the horizontal projection of each of the pipe segments between the air valve and the drain or rupture - m

Now, we calculate the new Δh by subtracting hf from the initial Δh:

4 . New Δh = Δh - hf

Use this New Δh in either equation 1 or equation 2 above (depending on the size of the drain valve or rupture, relative to the pipe diameter),

and calculate the final Q d.

Given that the air valve diameter required must be calculated separately for each separate air point in the system, the scope of the calculation work required is very considerable. To solve this problem, A.R.I. has developed a unique program – ARIavCAD. The ARIavCAD program determines the diameter and the location for each air valve and selects from the range of valves manufactured by A.R.I., the most appropriate air valve for installation at each point. Use of the ARIavCAD program is highly recommended. For further details, please contact the A.R.I. Service Department.

INTRODUCTION

Check ValvesOne-way or check valves are liquid direction devices that allow one-directional flow in the pipeline.

Check valves have various uses such as:- Controlling directions of flow of liquid in systems in which there are different sources of supply.- Preventing reverse flow into pumps when pump operation stops.- Maintaining down-stream pipe pressure in case of a pressure drop at the supply source.- Preventing drainage from high to low areas.

There are various types of check valves:- Swing-type check valves, check valves with top covers, check valves with a tilting disc, dual-leaf check valves, wafer type check valves, spring-loaded check valves, etc.All one-directional valves are built from a basic combination of a body (straight or angular) connected to piping and to a one-way sealing mechanism. The valves are distinguished from one another by the structure of the body and the various sealing mechanisms.The purpose of the various types of check valves is to provide solutions and adaptations for various applications.The R&D, engineering and manufacturing divisions of A.R.I. worked together to develop a basket of check valves for a variety of applications. They meet the needs of designers, installers, users and maintenance personnel. A.R.I. check valves are adapted for industry, wastewater, desalination, hot water, contaminated water, seawater, agricultural and gardening applications, potable water, water treatment systems, municipal lines and oil installations on offshore platforms.

Top-cover type check valves are designed to contend with aggressive environments and solids-laden liquid:1. The body and cover are cast from a variety of corrosion-resistant materials which cover a wide range of chemicals.2. The body has a barrel-shaped structure that allows unrestricted flow.3. A sealing mechanism incorporates a disc that opens fully even under low flow rates and swings up and out of the flow path (full flow). These two properties:

- enable for the flow of solids-laden liquids without blockage or stagnation, AND- ensure particularly low head losses (in the range of only a few centimeters), resulting in large energy savings.

4. The top cover provides access for inspection and maintenance without the need for dismantling the valve from the pipeline.5. The sealing seat assembly is accessible for replacement without dismantling the valve from the line.6. The internal configuration inhibits cavitation.7. The shaft that hinges the disc extends from the body of the valve. It serves for mounting counter weights which regulate the closing time of the disc, and greatly reduce the effects of slam and surge.8. The enhanced bearing assembly is unique and the shaft sealing is reliable and long-lasting. 9. The hinged arm is connected to the disc by two pins that prevent premature wear of the sealing assembly.10. A variety of structural materials are used in the sealing mechanism, the disc, and the sealing seat.11. Interior and exterior coatings are resistant to corrosion, chemicals and to UV.

Typical installation locations:- In pumping stations for raw wastewater.- In pumping stations for untreated water.- In desalination installations.- In chemical process piping systems to regulate the direction of flow.- Dividing the pressure between the two ends of long pipe segments in which there are large differences in elevation between the ends.

Combination Air Valve for High Pressure

Description The D-014, D-015, D-016, D-100 series Combination Air Valve has the features of both an air release valve and an air & vacuum valve. The air release component is designed to automatically release small pockets of air to the atmosphere as they accumulate along a pipeline or piping system when it is full and operating under pressure.The air & vacuum component is designed to automatically discharge or admit large volumes of air during the filling or draining of a pipeline or piping system. This valve will open to relieve negative pressures whenever water column separation occurs.

Applications Municipal and industrial high pressure water conveyance systems.

Operation The air & vacuum component, with the large orifice, discharges air at high flow rates during the filling of the system and admits air into the system at high flow rates during its drainage and at water column separation.High velocity air will not blow the float shut. Water will lift the float which seals the valve.At any time during system operation, should internal pressure of the system fall below atmospheric pressure, air will enter the system.The smooth discharge of air reduces pressure surges and other destructive phenomena.The intake of air in response to negative pressure protects the system from destructive vacuum conditions and prevents damage caused by water column separation. Air entry is essential to efficiently drain the system.The air release component releases entrapped air in pressurized systems.Without air valves, pockets of accumulated air may cause the following hydraulic disturbances: - Restriction of effective flow due to a throttling effect as would a partially closed valve. In extreme cases this will cause complete flow stoppage.- Obstruction of efficient hydraulic transmission due to air flow disturbances.- Accelerate cavitation damages.- Pressure transients and surges.- Corrosion in pipes, fittings and accessories.- Danger of a high-energy burst of compressed air.- Inaccuracies in flow metering.As the system starts to fill, the valve functions according to the following stages:1. Entrapped air in the pipeline is discharged by the valve.2. Liquid enters the valve, lifting the float which pushes the sealing

mechanism to its sealing position.3. Entrapped air, which accumulates at peaks and along the system, rises to the top of the valve, which in turn displaces the liquid in the valve’s body. 4. The float descends, unsealing the rolling seal. The air release orifice opens and the accumulated air is released.5. Liquid enters the valve and the float rises, pushing the rolling seal back to its sealing position.When internal pressure falls below atmospheric pressure (negative pressure):1. The floats will immediately drop down, opening the air & vacuum and air release orifices.2. Air will enter the system.

Main Features - Working pressure range: D-014: 0.2 - 40 barD-015: 0.2 - 25 bar / 0.2 - 40 bar / D-016: 0.2 - 64 bar - Testing Pressure: 1.5 times the working pressure of the air valve.- Maximum working temperature: 60° C.- Maximum intermittent temperature: 90° C.- Reliable operation reduces water hammer incidents. - Dynamic design allows for high velocity air discharge while preventing premature closure.- Lightweight, small dimensions, simple and reliable structure. - Special orifice seat design: combination of bronze and E.P.D.M. rubber assures long-term maintenance-free operation. - The discharge outlet enables removal of excess fluids.

Combination Air Valve for Low Pressure

What is a low pressure air valve? The low pressure air valve sealing mechanism is built with a very soft and sensitive seal. On one hand, it enables the full and effective discharge of air and, on the other hand, the air valve will close and seal tightly when water fills the valve, even if the water pressure is particularly low. Most other air valves are built so that it takes a higher minimum sealing pressure to effectively seal the valve. The A.R.I. air valve requires a minimum water pressure of just 0.2 bar to effectively seal. Low pressure air valves are designed to prevent water leaks through the discharge orifice of the air valve.

Description The D-040 LP series Combination Air Valve has the features of both an air release valve and an air & vacuum valve.The air release component is designed to automatically release small pockets of air to the atmosphere as they accumulate along a pipeline or piping system when it is full and operating under pressure.The air & vacuum component is designed to automatically discharge or admit large volumes of air during the filling or draining of a pipeline or piping system. This valve will open to relieve negative pressures whenever water column separation occurs.

Applications The D-040 LP is designed for installation on:1. Outlets from storage ponds and reservoirs.2. Topographic high points where water pressures are lower than 2 meters.3. Points on a pipeline of variable pressures, where pressures can drop below 2 meters.4. Topographical points on a pipeline that are close to the hydraulic grade line pressure. 5. The top of water tanks

Operation The air & vacuum component, with the large orifice, discharges air at high flow rates during the filling of the system and admits air into the system at high flow rates during its drainage and at water column separation.High velocity air will not blow the float shut. Water will lift the float, which seals the valve.At any time during system operation, should internal pressure of the system fall below atmospheric pressure, air will enter the system.The smooth discharge of air reduces pressure surges and other destructive phenomena.The intake of air in response to negative pressure protects the system from destructive vacuum conditions and prevents damage caused

by water column separation. Air entry is essential to efficiently drain the system. The air release component releases entrapped air in pressurized systems.Without air valves, pockets of accumulated air may cause the following hydraulic disturbances: : - Restriction of effective flow due to a throttling effect as would a partially closed valve. In extreme cases this will cause complete flow stoppage.- Obstruction of efficient hydraulic transmission due to air flow disturbances.- Accelerate cavitation damages.- Pressure transients and surges.- Corrosion in pipes, fittings and accessories.- Danger of a high-energy burst of compressed air.- Inaccuracies in flow metering.As the system starts to fill, the valve functions according to the following stages:1. Entrapped air in the pipeline is discharged by the valve.2. Liquid enters the valve, lifting the float which pushes the sealing mechanism to its sealing position.3. Entrapped air, which accumulates at peaks and along the system, rises to the top of the valve, which in turn displaces the liquid in the valve’s body. 4.

Liquid enters the valve and the float rises, pushing the rolling seal back to its sealing position.When internal pressure falls below atmospheric pressure (negative pressure):1. The float will immediately drop down, opening the air & vacuum and air release orifices.2. Air will enter the system.

Main Features - Working pressure range: 0.05 - 6 bar.- Testing pressure: 10 bar.- Maximum working temperature: 60° C. - Maximum intermittent temperature: 90° C.- Reliable operation reduces water hammer incidents. - Dynamic design allows for high velocity air discharge while preventing premature closure.- Lightweight, small dimensions, simple and reliable structure.- The drainage outlet enables removal of excess fluids. - The large size of the automatic air release orifice relative to the air valve body:• Discharges air at high flow rates.

DescriptionThe D-090-P Underground Air Valve is designed to save the costs of manholes and provide reliable solutions for special requirements such as:- Frost protection.- Savings in installation costs.- Installation under important crossings, including: roads, pavements, buildings.- Eliminate the need for confined-space entry - its costs and safety demands.

Operation The air & vacuum component, with the large orifice, discharges air at high flow rates during the filling of the system and admits air into the system at high flow rates during its drainage and at water column separation.High velocity air will not blow the float shut. Water will lift the float which seals the valve.At any time during system operation, should internal pressure of the system fall below atmospheric pressure, air will enter the system.The smooth discharge of air reduces pressure surges and other destructive phenomena.The intake of air in response to negative pressure protects the system from destructive vacuum conditions and prevents damage caused by water column separation. Air entry is essential to efficiently drain the system.The automatic air release component releases entrapped air in pressurized systems.

Without air valves, pockets of accumulated air may cause the following hydraulic disturbances:- Restriction of effective flow due to a throttling effect as would a partially closed valve. In extreme cases this will cause complete flow stoppage.- Obstruction of efficient hydraulic transmission due to air flow disturbances.- Accelerate cavitation damages.- Pressure transients and surges.- Corrosion in pipes, fittings and accessories.- Danger of a high-energy burst of compressed air.- Inaccuracies in flow metering.

As the system starts to fill, the valve functions according to the following stages:1. Entrapped air in the pipeline is discharged by the valve.2. Liquid enters the valve, lifting the float which pushes the sealing

mechanism to its sealing position.3. Entrapped air, which accumulates at peaks and along the system, rises to the top of the valve, which in turn displaces the liquid in the valve’s body. 4. The float descends, unsealing the rolling seal. The air release orifice opens and the accumulated air is released.5. Liquid enters the valve and the float rises, pushing the rolling seal back to its sealing position.

M-040 PN 10

Combination Air Valve for Water Meter Protection “Metair”

Description The M-040 Combination Air Valve combines an air & vacuum orifice with an automatic air release orifice in one single body.The combination air valve discharges air during the filling of the system and admits air during drainage and pump shutoff while releasing accumulated air from the system while the system is operating under pressure.The M-040 Combination Air Valve is designed to prevent problems caused by discontinuous or erratic water supply: - Erroneous water metering. - Damage to the spinning components of the water meter. - Vibrations and water hammer in the pipeline and water meter.

Applications - On a pressurized piping system, installed before the water meter.

OperationOVERVIEW: The M-040 combination air valve is normally closed. When water supply is erratic and air builds up in the system, the M-040 prevents the air from passing through the water meter by releasing this accumulated air from the pipeline to the atmosphere. As water returns, it buoys the float, sealing the outlet to the atmosphere, opening the check valve and allowing the water to pass through water meter. The air & vacuum component, with the large orifice, discharges air at high flow rates during the filling of the system and admits air into the system at high flow rates during its drainage and at water column separation.High velocity air will not blow the float shut. Water will lift the float which seals the valve.At any time during system operation, should internal pressure of the system fall below atmospheric pressure, air will enter the system.The smooth discharge of air reduces pressure surges and other destructive phenomena.The intake of air in response to negative pressure protects the system from destructive vacuum conditions and prevents damage caused by water column separation. Air entry is essential to efficiently drain the system.The automatic small orifice air release component releases entrapped air in pressurized systems.

Without air valves, pockets of accumulated air may cause the following hydraulic disturbances: - Restriction of effective flow due to a throttling effect as would a partially closed valve. In extreme cases this will cause complete flow stoppage.

- Obstruction of efficient hydraulic transmission due to air flow disturbances.- Accelerate cavitation damages.- Pressure transients and surges.- Corrosion in pipes, fittings and accessories.- Danger of a high-energy burst of compressed air.- Inaccuracies in flow metering.As the system starts to fill, the valve functions according to the following stages:1. Entrapped air in the pipeline is discharged by the valve.2. Liquid enters the valve, lifting the float which pushes the sealing mechanism to its sealing position.3. Entrapped air, which accumulates at peaks and along the system, rises to the top of the valve, which in turn displaces the liquid in the valve’s body. 4. The float descends, unsealing the rolling seal. The air release orifice opens and the accumulated air is released.5. Liquid enters the valve and the float rises, pushing the rolling seal back to its sealing position.


Main Features - Working range: 0.2 - 10 bar - Testing pressure: 16 bar.- Maximum working temperature: 60° C. - Maximum intermittent temperature: 90° C.- Lightweight and small, made of corrosive-resistant composite materials. - Spring-loaded check valve opens at 0.25 bar water pressure in the direction of the water meter. The check valve assures effective air trapping and prevents water drainage from the water meter. - User-friendly integral shutoff valve: an innovative built- in shut off valve in the valve cap enables the isolation of the air valve orifice with no interference to the water flow in the pipeline. - Drainage System: Optional drainage outlet or screen outlet. - The large orifice, with its self-cleaning mechanism, dramatically reduces obstruction due to debris.- Integral air trapping non-return valve.- Dynamic design allows high velocity air discharge while preventing premature closure

D-050 LP PN 6

DescriptionThe D-050 LP Combination Air Valve has the features of both an air release valve and an air & vacuum valve.The air release component is designed to automatically release small pockets of air to the atmosphere as they accumulate along a pipeline or piping system when it is full and operating under pressure.The air & vacuum component is designed to automatically discharge or admit large volumes of air during the filling or draining of a pipeline or piping system. This valve will open to relieve negative pressures whenever water column separation occurs.

Applications - Municipal and industrial water conveyance systems.- Low pressure systems.

OperationThe air & vacuum component, with the large orifice, discharges air at high flow rates during the filling of the system and admits air into the system at high flow rates during its drainage and at water column separation.High velocity air will not blow the float shut. Water will lift the float which seals the valve.At any time during system operation, should internal pressure of the system fall below atmospheric pressure, air will enter the system.The smooth discharge of air reduces pressure surges and other destructive phenomena.The intake of air in response to negative pressure protects the system from destructive vacuum conditions and prevents damage caused by water column separation. Air entry is essential to efficiently drain the system.The air release component releases entrapped air in pressurized systems.Without air valves, pockets of accumulated air may cause the following hydraulic disturbances: - Restriction of effective flow due to a throttling effect as would a partially closed valve. In extreme cases this will cause complete flow stoppage.- Obstruction of efficient hydraulic transmission due to air flow disturbances.- Accelerate cavitation damages.- Pressure transients and surges.- Corrosion in pipes, fittings and accessories.- Danger of a high-energy burst of compressed air.- Inaccuracies in flow metering.



Main Features- Working pressure range: 0.05 - 6 bar - Testing pressure: 10 bar.- Maximum working temperature: 60° C. - Maximum intermittent temperature: 90° C.- Reliable operation reduces water hammer incidents. - Dynamic design allows for high velocity air discharge while preventing premature closure.- Lightweight, small dimensions, simple and reliable structure. - Special orifice seat design: combination of bronze and E.P.D.M. rubber assures long-term maintenance-free operation. - The drainage outlet enables removal of excess fluids (2" - 8").

Air Release Component- Body made of high strength materials.- All operating parts are made of specially selected corrosion- resistant polymer materials.- Large sized air release orifice:• Dramatically reduces the possibility of obstruction by debris.• Discharges high air flow rates.• One size orifice for a wide pressure range (up to 25 bar), achieved by the A.R.I. patented rolling seal mechanism.

This valve will open to relieve negative pressures whenever water column separation occurs.


D-060-C, D-062, D-065 - additional applications- Water pipelines vulnerable to vandalism and/or water theft.- Water systems found in remote areas.- Water systems with pressure demands of 25 & 40 bar (D-062 & D-065 respectively).


Without air valves, pockets of accumulated air may cause the following hydraulic disturbances: - Restriction of effective flow due to a throttling effect as would a

partially closed valve. In extreme cases this will cause complete flow stoppage.- Obstruction of efficient hydraulic transmission due to air flow disturbances.- Accelerate cavitation damages.- Pressure transients and surges.- Corrosion in pipes, fittings and accessories.- Danger of a high-energy burst of compressed air.- Inaccuracies in flow metering.

As the system starts to fill, the valve functions according to the following stages:1. Entrapped air in the pipeline is discharged by the valve.2. Liquid enters the valve, lifting the float which pushes the sealing mechanism to its sealing position.3. Entrapped air, which accumulates at peaks and along the system, rises to the top of the valve, which in turn displaces the liquid in the valve's body. 4. The float descends, unsealing the rolling seal. The air release orifice opens and the accumulated air is released.5. Liquid enters the valve and the float rises, pushing the rolling seal back to its sealing position.


Main Features - Working pressure range: D-060 0.2 - 16 bar D-060-C 0.2 - 16 bar D-062 0.2 - 25 bar D-065 0.2 - 40 bar- Testing pressure for the air valve is 1.5 times its working pressure.- Maximum working temperature: 60° C. - Maximum intermittent temperature: 90° C.- All main flow cross-sections are equal or greater than the nominal port area.

Underground Air Valve System for Potable Water

Description The D-060 SB is a complete product package that combines the reliable and efficient properties of the A.R.I. D-060 Combination Air Valve with the added feature of a sub-surface valve that can be buried below ground. A specially designed gear box operated horizontal sliding disc valve - situated at the base of the D-060 SB assembly - allows for the air valve disconnection and maintenance from ground level. This gear box operated shut-off valve is equipped with a safety mechanism enabling disconnection and removal of the D-060 air valve from its subsurface housing, even when the system is under pressure. Since service and maintenance operations of the unit are performed entirely from the surface, there is no need for safety considerations associated with confined space entry.The D-060 Combination Air Valve has the features of both an air release valve and an air & vacuum valve.The air release component is designed to automatically release small pockets of air to the atmosphere as they accumulate along a pipeline or piping system when it is full and operating under pressure.The air & vacuum component is designed to automatically discharge or admit large volumes of air during the filling or draining of a pipeline or piping system. This valve will open to relieve negative pressures whenever water column separation occurs.


OperationThe air & vacuum component, with the large orifice, discharges air at high flow rates during the filling of the system and admits air into the system at high flow rates during its drainage and at water column separation.High velocity air will not blow the float shut. Water will lift the float, which seals the valve.At any time during system operation, should internal pressure of the system fall below atmospheric pressure, air will enter the system.The smooth discharge of air prevents pressure surges and other destructive phenomena.The intake of air in response to negative pressure protects the system from a destructive downsurge (vacuum conditions) and prevents damage caused by water column separation. Air entry is essential to efficiently drain the system.The air release component releases entrapped air in pressurized systems.


The air valve functions according to the following stages:1. As water fills the system, air in the pipeline is discharged by the air valve.2. Liquid enters the air valve, lifting the floats which push the sealing mechanisms to their sealing position.3. Entrapped air that accumulates along the system rises to the top of the air release valve, which in turn displaces the liquid in the valve’s body. 4. The float descends, unsealing the rolling seal. The air release orifice opens and the accumulated air is released.5. Liquid enters the air release valve and the float rises, pushing the rolling seal back to its sealing position.


Main Features D-060 SB Underground Air Valve System for Potable Water:

- The D-060 SB incorporates an integral, flat, gear box operated horizontal sliding disc valve with a 2”, 3” full bore passage.

- The shut-off valve is operated from the surface.

- The quick connector between the adaptor and the shut-off valve facilitates detachment during handling.

- The integrated assembly handle eases the process of lifting the air valve assembly out from the valve box.

- Pipe connections: 3” threaded (BSP/NPT) or flanged, in accordance with all standards.

Combination Air Valve for High Flow - Non Slam

Description The D-060 NS series Combination Air Valve has the features of both an air release valve and an air & vacuum valve.The air release component is designed to automatically release small pockets of air to the atmosphere as they accumulate along a pipeline or piping system when it is full and operating under pressure.The air & vacuum component is designed to automatically discharge or admit large volumes of air during the filling or draining of a pipeline or piping system. This valve will open to relieve negative pressures whenever water column separation occurs.

Applications - Water pipelines with anticipated conditions of surge and water hammer. - On the peaks of water pipelines with steep slopes.- Water pipelines where water column separation occurs.

D-060-C - additional applications- Water pipelines vulnerable to vandalism and/or water theft.- Water systems found in remote areas.D-062 NS and D-065 NS - additional applications- Water systems with pressure demands of 25 bar and 40 bar (D-062 NS and D-065 NS respectively).

Operation The D-060 HF NS series Combination Non Slam Air Valve is a surge-dampening, slam-preventing, 3-stage combination air valve. The air valve provides high capacity vacuum protection and, at the same time, efficient surge suppression. At sudden drainage and/or water column separation (sudden pump trips or valve closure, for instance), the air & vacuum orifice admits air at high flow rates, thus preventing vacuum. As the water column and/or pressure wave returns, large volumes of air are discharged at high velocities, raising the non-slam disc, partially closing the air & vacuum orifice and allowing air to exhaust slowly through the smaller orifice of the non-slam disc. This slowly exhausting air pocket dampens the slam of the returning water column, thus suppressing the pressure surge. As the water flow arrives at a much slower rate, dampened by the slower air discharge, it buoys up the main float, gently closing the air & vacuum component of the air valve. The S-050-C, S-052, S-015 air release component continues releasing air while the pipeline and the air valve are pressurized.

Main Features - Working pressure range: D-060 NS: 0.2 -16 bar D-060-C NS: 0.2 - 16 bar D-062 NS: 0.2 - 25 bar D-065 NS: 0.2 - 40 bar - Testing pressure for the air valve is 1.5 times its working pressure.- Maximum working temperature: 60° C. - Maximum intermittent temperature: 90° C.- All main flow cross-sections are equal or greater than the nominal port area.- Aerodynamic design enables high flow rates of air both at intake and at discharge.- Reliable operation reduces water hammer incidents. - Dynamic design allows for high velocity air discharge while preventing premature closure.- Special orifice seat design: bronze and E.P.D.M. rubber, assures long-term maintenance-free operation. - Screen protected outlet.- The upper screen is protected with a protective cover.- FBE coating, both interior & exterior, according to the standard DIN 30677-2. Air Release Component - Body made of high strength materials.- All operating parts are made of specially selected corrosion- resistant polymer materials.- Large sized air release orifice:• Dramatically reduces the possibility of obstruction by debris.• Discharges high air flow rates.• One size orifice for a wide pressure range (up to 40 bar), achieved by the A.R.I. patented rolling seal mechanism.

Valve Selection - Size Range: 1”- 10” 2” – 8” (for model D-065 NS only)- D-060 NS, for 16 bar- D-060-C NS vandalism protected by a metal shell covering the air release component, made for 16 bar.- D-062 NS vandalism protected by a metal shell covering the air release component, made for 25 bar.- D-065 NS, made for 40 bar.- These valves are manufactured with flanged ends to meet any requested standard.

- The 2” valve is also available with a threaded BSP or NPT connection. - Valve coating: fusion bonded epoxy coating according to the standard DIN 30677-2.- Other coatings are available upon request.- The automatic air release component and the air & vacuum component are available as separate units.- For best suitability, it is recommended to send the fluid chemical properties along with the valve request.


Non-Slam DiscThe built- in throttling device on the Non-Slam disc of the D-060 HF NS Combination Air Valves will allow for the graduated opening and closing of the disc orifice.

Advantages:1. The orifice size of the disc can be adjusted to control and throttle the discharge of air during pipeline filling and during the return of the water column after separation. 2. The controlled discharge of air will reduce surge effects and provide for a silent closure of the air valve. 3. The closure of the orifice can be determined by running a surge analysis or by a decision taken in the field.4. The orifice throttling device allows for a wide range of options from 100% open, partially open, partially closed to 100% closed.

1. When water, rapidly filling the pipe line, pushes the air out through the Air Valve, a differential air pressure is created across the valve orifice.

Operation in Rapid Filling of the Pipeline:

6. When water is drained out of the pipe line, the resulting pressure drop lets the kinetic float fall down, opening the orifice fully for intake of high volume of air into the line.

4. When water reaches the kinetic float, it lifts it up, closing the kinetic orifice and completing the kinetic cycle.5. The «vented Check Valve Orifice Disc» will come back to its normal open position.

2. When this differential pressure reaches a prefixed level (usually it will be prefixed at 0.02 - 0.03 bar) the orifice disc will close.3. Air will continue to come out through the small orifice disc - until all the air will be exhausted and water will reach the kinetic float. This double stage kinetic air discharge prevents the slam effect and therefore suppresses water hammer.

Combination Air Valve - Non Slam

Description The D-060 NS M1 series Combination Air Valve has the features of both an air release valve and an air & vacuum valve.The air release component is designed to automatically release small pockets of air to the atmosphere as they accumulate along a pipeline or piping system when it is full and operating under pressure.The air & vacuum component is designed to automatically discharge or admit large volumes of air during the filling or draining of a pipeline or piping system. This valve will open to relieve negative pressures whenever water column separation occurs.

Applications - Water pipelines with anticipated conditions of surge and water hammer. - On the peaks of water pipelines with steep slopes.- Water pipelines where water column separation occurs.

D-060-C NS M1 - additional applications- Water pipelines vulnerable to vandalism and/or water theft.- Water systems found in remote areas.D-062 NS M1 - additional applications- Water systems with pressure demands of 25 bar (D-062 NS M1 respectively).D-065 NS M1 - additional applications- Water systems with pressure demands of 40 bar (D-065 NS M1respectively).

Operation The D-060 NS M1 series Combination Non Slam Air Valve is a surge-dampening, slam-preventing, 3-stage combination air valve. The air valve provides high capacity vacuum protection and, at the same time, efficient surge suppression. At sudden drainage and/or water column separation (sudden pump trips or valve closure, for instance), the air & vacuum orifice admits air at high flow rates, thus preventing vacuum. As the water column and/or pressure wave returns, large volumes of air are discharged at high velocities, raising the non-slam disc, partially closing the air & vacuum orifice and allowing air to exhaust slowly through the smaller orifice of the non-slam disc. This slowly exhausting air pocket dampens the slam of the

returning water column, thus suppressing the pressure surge. As the water flow arrives at a much slower rate, dampened by the slower air discharge, it buoys up the main float, gently closing the air & vacuum component of the air valve. The S-050, S-050-C, S-052, S-015 air release component continues releasing air while the pipeline and the air valve are pressurized.

Main Features - Working pressure range: D-060 NS M1: 0.2-16 bar D-060-C NS M1: 0.2-16 bar D-062 NS M1: 0.2-25 bar D-065 NS M1: 0.2-40 bar - Testing pressure for the air valve is 1.5 times its working pressure.- Maximum working temperature: 60° C. - Maximum intermittent temperature: 90° C.- All main flow cross-sections are equal or greater than the nominal port area.- Aerodynamic design enables high flow rates of air both at intake and at discharge.- Reliable operation reduces water hammer incidents. - Dynamic design allows for high velocity air discharge while preventing premature closure.- Special orifice seat design: bronze and E.P.D.M. rubber, assures long-term maintenance-free operation. - Screen protected outlet.- The upper screen is protected with a protective cover.- FBE coating, both interior & exterior, according to the standard DIN 30677-2.

Air Release Component - Body made of high strength materials.- All operating parts are made of specially selected corrosion- resistant polymer materials.- Large sized air release orifice:• Dramatically reduces the possibility of obstruction by debris.• Discharges high air flow rates.• One size orifice for a wide pressure range (up to 25 bar), achieved A.R.I patented rolling seal mechanism.

Underground Air Valve System for Potable Water

Description The D-060NS SB is a complete product package that combines the reliable and efficient properties of the A.R.I. D-060 NS Combination Air Valve with the added feature of a sub-surface valve that can be buried below ground. A specially designed gear box operated horizontal sliding disc valve - situated at the base of the D-060 NS SB assembly - allows for the air valve disconnection and maintenance from ground level. This gear box operated shut-off valve is equipped with a safety mechanism enabling disconnection and removal of the D-060NS air valve from its subsurface housing, even when the system is under pressure. Since service and maintenance operations of the unit are performed entirely from the surface, there is no need for safety considerations associated with confined space entry.The D-060 NS series Combination Non Slam Air Valve is a surge-dampening, slam-preventing, 3-stage combination air valve. The air valve provides high capacity vacuum protection and, at the same time, efficient surge suppression. The air release component is designed to automatically release small pockets of air to the atmosphere as they accumulate along a pipeline or piping system when it is full and operating under pressure.The air & vacuum component is designed to automatically discharge or admit large volumes of air during the filling or draining of a pipeline or piping system. This valve will open to relieve negative pressures whenever water column separation occurs.The non slam component is designed to throttle air discharge through the smaller orifice of the non-slam disc to prevent surge.


OperationThe D-060 NS series Combination Non Slam Air Valve is a surge-dampening, slam-preventing, 3-stage combination air valve. The air valve provides high capacity vacuum protection and, at the same time, efficient surge suppression. 1. At sudden drainage and/or water column separation (sudden pump trips or valve closure, for instance), the air & vacuum orifice admits air at high flow rates, thus preventing vacuum. 2. As the water column and/or pressure wave returns, large volumes of air are discharged at high velocities, raising the non-slam disc, partially closing the air & vacuum orifice and allowing air to exhaust slowly through the smaller orifice of the non-slam disc.

3. This slowly exhausting air pocket dampens the slam of the returning water column, thus suppressing the pressure surge. 4. As the water flow arrives at a much slower rate, dampened by the slower air discharge, it buoys up the main float, gently closing the air & vacuum component of the air valve. 5. The S-050 / S-050-C / S-052 air release component continues releasing air while the pipeline and the air valve are pressurized.


Main Features D-060 NS SB Underground Air Valve System for Potable Water:

- The D-060 NS SB incorporates an integral, flat, gear box operated horizontal sliding disc valve with a 2”, 3” full bore passage.


- The quick connector between the adaptor and the shut-off valve facilitates detachment during handling.

- The integrated assembly handle eases the process of lifting the air valve assembly out from the valve box.


- Safety elements: Disengaging the air valve is safeguarded: unless the shut-off valve is in the “closed” position and the internal pressure is released, it is not possible to extract the air valve.

- All parts are corrosion resistant: Metal parts made of Stainless Steel, Ductile Iron or steel, Composite material parts made of Nylon.

Dynamic Combination Air Valve PATENTED

Description The D-070 Dynamic Combination Air Valve is a unique valve, operating without a float and utilizing the rolling diaphragm principle. This unique structure allows the dynamic air valve to discharge air from the water system in a controlled and gradual manner, thus preventing slam and local up-surges. When vacuum (down-surge) occurs, the valve reacts quickly to admit large volumes of air into the water system, thus impeding down-surges and, consequently, all pressure surges in the line. The air & vacuum component of the dynamic air valve is normally closed when the line is not operating, thus preventing the infiltration of debris and insects into the water system.

Applications - Pumping stations, deep wells and distribution lines. - Systems that are prone to slam and local and system surges. - Sites that require a combination of means to reduce water hammer or surges. - Sites that require an air valve with a low profile due to lack of space.

OperationWhen the system is charged and the pipeline begins to fill with water, air flows in the pipeline and enters into the dynamic air valve, raising the rolling diaphragm sealing assembly to the open position. Air is then discharged, mainly out through the lower chamber large orifice as well as small amounts of air released out through upper chamber operating valve orifice. When the ensuing water enters the dynamic air valve, it fills the lower chamber and some of it flows up through the orifice chamber and enters into the upper operating chamber, raising the float of the operating valve which rolls the sealing mechanism to its sealed position. Pressure develops inside the upper operating chamber, bringing about a controlled lowering and sealing of the rolling diaphragm sealing assembly, which, in turn, closes the lower chamber large orifice.NOTE: It is recommended to attach a drainage pipe to the connection on the large orifice outlet as some water will be expelled from the orifice during this closure stage. The size of the drainage pipe should be, at a minimum, the diameter of the outlet and the unattached end should remain open to the atmosphere.

At this stage, only the automatic air release component continues to function and releases air through its small orifice. With a reduction in line pressure, during drainage or shut-off, the pressure in the valve is reduced and is lower then the outside atmospheric pressure. The vacuum created will cause the rolling diaphragm

sealing assembly to rise up into its open position, opening the lower chamber large orifice and allowing the intake of air from the atmosphere into the system.

Main Features - Working pressure range: 0.2 - 16 bar. - Testing pressure: 25 bar. - Maximum working temperature: 60° C. - Maximum intermittent temperature: 90° C.- Internal components are corrosion-resistant.- Prevents slam and reduces water surges in the air valve and the pipeline. - Prevents the intrusion of debris and contaminants into the system. - Valve is lightweight and small for easy installation; its operation simple and reliable. - Built-in connection at the outlet for surplus water drainage. - Smooth and gradual closing unaffected by water flow. - Extremely quiet closing. - Automatic air release component releases large quantities of air without becoming obstructed.

Valve Selection - Sizes: 3”, 4”, 6”, 8” and 12”.- Valves are manufactured with flanged ends to meet any requested standard. - Valve coating: fusion bonded epoxy coating according to the standard DIN 30677-2.- Other coatings are available upon request.- Optional D-070 P – Sizes: 2”, 3” (threaded or flanged) & 4” (flanged only); made of composite materials (suitable for agricultural installations) with a working pressure: 0.2 - 10 bar. - Optional one-way D-070-I valve - intakes air only, without allowing air discharge. - For best fit, it is recommended that the composition of liquids and system requirements be defined in advance.

When ordering, please indicate the model, dimensions, working pressure, threading/flange standard and special coatings.

D-070 M1 PN 16


Description The D-070 M1 Dynamic Combination Air Valve is a unique valve, operating without a float and utilizing the rolling diaphragm principle. This unique structure allows the dynamic air valve to discharge air from the water system in a controlled and gradual manner, thus preventing slam and local up-surges. When vacuum (down-surge) occurs, the valve reacts quickly to admit large volumes of air into the water system, thus impeding down-surges and, consequently, all pressure surges in the line. The air & vacuum component of the dynamic air valve is normally closed when the line is not operating, thus preventing the infiltration of debris and insects into the water system.

Applications - Pumping stations, deep wells and distribution lines. - Systems that are prone to slam and local and system surges. - Sites that require a combination of means to reduce water hammer or surges. - Sites that require an air valve with a low profile due to lack of space.

OperationWhen the system is charged and the pipeline begins to fill with water, air flows in the pipeline and enters into the dynamic air valve, raising the rolling diaphragm sealing assembly to the open position. Air is then discharged, mainly out through the lower chamber large orifice as well as small amounts of air released out through upper chamber operating valve orifice. When the ensuing water enters the dynamic air valve, it fills the lower chamber and some of it flows up through the orifice chamber and enters into the upper operating chamber, raising the float of the operating valve which pushes the sealing mechanism to its sealed position. Pressure develops inside the upper operating chamber, bringing about a controlled lowering and sealing of the rolling diaphragm sealing assembly, which, in turn, closes the lower chamber large orifice.NOTE: It is recommended to attach a drainage pipe to the connection on the large orifice outlet as some water will be expelled from the orifice during this closure stage. The size of the drainage pipe should be, at a minimum, the diameter of the outlet and the unattached end should remain open to the atmosphere.

At this stage, only the automatic air release component continues to function and releases air through its small orifice. With a reduction in line pressure, during drainage or shut-off, the pressure in the valve is reduced and is lower then the outside atmospheric pressure. The vacuum created will cause the rolling diaphragm

sealing assembly to rise up into its open position, opening the lower chamber large orifice and allowing the intake of air from the atmosphere into the system.

Main Features - Working pressure range: 0.2 - 16 bar. - Testing pressure: 25 bar. - Maximum working temperature: 60° C. - Maximum intermittent temperature: 90° C.- Internal components are corrosion-resistant. - Prevents slam and reduces water surges in the air valve and the pipeline. - Prevents the intrusion of debris and contaminants into the system. - Valve is lightweight and small for easy installation; its operation simple and reliable. - Built-in connection at the outlet for surplus water drainage. - Smooth and gradual closing unaffected by water flow. - Extremely quiet closing. - Automatic air release component releases large quantities of air without becoming obstructed.

Valve Selection - Sizes: 4", 6", 8" and 10".- Valves are manufactured with flanged ends to meet any requested standard. - Optional :D-070 – sizes : 3” – 8” , 12"D-070 P – Sizes: 2”, 3” (threaded or flanged) & 4” (flanged only); made of composite materials with a working pressure: 0.2 - 10 bar. - Valve coating: fusion bonded epoxy coating according to the standard DIN 30677-2.- Other coatings are available upon request.- Additional one-way D-070 M1-I valve - intakes air only, without allowing air discharge. - For best fit, it is recommended that the composition of liquids and system requirements be defined in advance.

When ordering, please indicate the model, dimensions, working pressure, threading/flange standard and special coatings.

Air & Vacuum ValveDescription The K-010 series Air & Vacuum Valve discharges air during the filling or charging of the system and admits air into the system during system drainage, valve or pump shut-off or at water column separation.


K-012 - K-100- Water conveyance systems requiring high pressure valves.

Operation The air & vacuum valve discharges air at high flow rates during the filling of the system and admits air at high flow rates during the drainage , pump shut-off or at water column separation.High velocity air will not blow the float shut. Water entry will cause the sealing of the valve.At any time during system operation, should internal pressure of the system fall below atmospheric pressure, air will enter the system.The smooth discharge of air prevents pressure surges and other destructive phenomena.The intake of air in response to negative pressure protects the system from destructive vacuum conditions and prevents damage caused by water column separation. Air entry is essential to efficiently drain the system.

As the system starts to fill, the valve functions according to the following stages:1. Entrapped air is discharged by the valve.2. The liquid enters the valve, lifting the float and sealing the valve.

When internal pressure falls below atmospheric pressure (negative pressure):1. The float will immediately drop down, opening the air & vacuum the orifice. 2. Air will enter the system.

Main Features - Working pressure range: 0.2 - 100 bar. - Testing Pressure: 1.5 times the working pressure of the air valve.- Maximum working temperature: 60° C. - Maximum intermittent temperature: 90° C.

- Reliable operation reduces water hammer incidents. - Dynamic design allows for high velocity air discharge while preventing premature closure.- Lightweight, small dimensions, simple and reliable structure. - Special orifice seat design: combination of bronze and E.P.D.M. rubber assures long-term maintenance-free operation. - The discharge outlet enables removal of excess fluids (2” - 8”).

Description The K-060 NS series Air & Vacuum Valve discharges air during the filling or charging of the system and admits air into the system during system drainage, valve or pump shut-off or at water column separation.

Applications - Municipal and industrial water conveyance systems.- Water pipelines vulnerable to vandalism and/or water theft.- Water systems found in remote areas.- Water systems with high pressure demands (K-062 NS, K-064 NS ).

Operation The air & vacuum valve discharges air at high flow rates during the filling of the system and admits air at high flow rates during the drainage , pump shut-off or at water column separation.High velocity air will not blow the float shut. Water entry will cause the sealing of the valve.At any time during system operation, should internal pressure of the system fall below atmospheric pressure, air will enter the system.The smooth discharge of air reduces pressure surges and other destructive phenomena.The intake of air in response to negative pressure protects the system from destructive vacuum conditions and prevents damage caused by water column separation. Air entry is essential to efficiently drain the system.



Main Features - Working pressure range: K-060 NS 0.2-16 bar K-062 NS 0.2-25 bar K-064 NS 0.2-40 bar- Testing pressure for the air valve is 1.5 times its working pressure.- Maximum working temperature: 60° C. - Maximum intermittent temperature: 90° C.- All main flow cross-sections are equal or greater than the nominal port area.- Aerodynamic design enables high flow rates of air both at intake and at discharge.- Reliable operation reduces water hammer incidents. - Dynamic design allows for high velocity air discharge while preventing premature closure.- Special orifice seat design: Stainless steel and E.P.D.M. rubber, assures long-term maintenance-free operation. - Screen protected outlet.- The upper screen is protected with a protective cover.- FBE coating, both interior & exterior, according to the standard DIN 30677-2.

Non-Slam DiscThe built- in throttling device on the Non-Slam disc of the D-060 HF NS Combination Air Valves will allow for the graduated opening and closing of the disc orifice.

Advantages:1. The orifice size of the disc can be adjusted to control and throttle the discharge of air during pipeline filling and during the return of the water column after separation. 2. The controlled discharge of air will reduce surge effects and provide for a silent closure of the air valve. 3 .The closure of the orifice can be determined by running a surge analysis or by a decision taken in the field.4. The orifice throttling device allows for a wide range of options from 100% open, partially open, partially closed to 100% closed.

1. When water, rapidly filling the pipe line, pushes the air out through the Air Valve, a differential air pressure is created across the valve orifice.

Operation in Rapid Filling of the Pipeline:

6. When water is drained out of the pipe line, the resulting pressure drop lets the kinetic float fall down, opening the orifice fully for intake of high volume of air into the line.

4. When water reaches the kinetic float, it lifts it up, closing the kinetic orifice and completing the kinetic cycle.5. The «vented Check Valve Orifice Disc» will come back to its normal open position.

2. When this differential pressure reaches a prefixed level (usually it will be prefixed at 0.02 - 0.03 bar) the orifice disc will close.3. Air will continue to come out through the small orifice disc - until all the air will be exhausted and water will reach the kinetic float. This double stage kinetic air discharge prevents the slam effect and therefore suppresses water hammer.

Automatic Air Release Valve for High-Pressure Systems

Description The S-014, S-015, S-016 series automatic air release valve releases accumulated air from the system while it is under pressure. The presence of air in a water system can reduce the effective cross sectional flow area resulting in increased head loss and flow. Unwanted air may also cause water hammer and metering inaccuracies, while hastening corrosion.

Applications - On high-pressure pumps. - On high-pressure delivery pipelines.

Operation The automatic air release valve releases entrapped air from pressurized systems.Pockets of accumulated air may cause the following destructive phenomena:- Impediment of effective flow and hydraulic conductivity of the system along with a throttling effect as would a partially closed valve. In extreme cases this will cause complete flow stoppage.- Accelerate cavitation damages.- High- pressure surges.- Accelerate corrosion.- Danger of a high-energy burst of compressed air.- Inaccuracies in flow metering.The valve functions while the system is under pressure, according to the following stages:1. Entrapped air, which accumulates at peaks and along the system, rises to the top of the valve, which in turn displaces the liquid in the valve’s body. 2. The float descends, unsealing the rolling seal. The automatic air release orifice opens and the accumulated air is released.3. Liquid enters the valve and the float rises, pushing the rolling seal back to its sealing position.Note: Automatic air release valves are designed to release air as it accumulates in pressurized systems. They are not normally recommended for vacuum protection or for discharging large volumes of air, because of their inherently small orifices. For this purpose, air & vacuum valves are recommended as they have much larger orifices.However, air release valves will permit air to enter the system under vacuum conditions. If this is not desirable, specify the one-way out check valve.

Main Features - Working pressure range: S-014: 0.2 - 40 bar S-015: 0.2 - 25 bar / 0.2 - 40 bar S-016: 0.2 - 64 bar- Test pressure for the air valve is 1.5 times its working pressure. - Maximum working temperature: 60° C. - Maximum intermittent temperature: 90° C.-All operating parts are made of specially selected corrosion-resistant materials. - A.R.I. patented rolling seal mechanism: • Dramatically reduces the possibility of obstruction by debris. • One size orifice for a wide pressure range up to 64 bar. • Self-cleaning mechanism. - Lightweight, small dimensions, simple and reliable structure.

Valve Selection - S-014 (40 bar), S-015 (25 / 40 bar), S-016 (64 bar) are available in 3/4”, 1”, male threaded BSP and NPT connections / flanged. - Standard metal body - FBE coating according to the standard DIN 30677-2.- Other coatings are available upon request.- For best suitability, it is recommended to send the fluid chemical properties along with the valve request.

Automatic Air Release Valve for Low Pressure

What is a low pressure air valve? The low pressure air valve sealing mechanism is built with a very soft and sensitive seal. On one hand, it enables the full and effective discharge of air and, on the other hand, the air valve will close and seal tightly when water fills the valve, even if the water pressure is particularly low. Most other air valves are built so that it takes a higher minimum sealing pressure to effectively seal the valve. The ARI air valve requires a minimum water pressure of just 0.2 bar (3psi) to effectively seal. Low pressure air valves are designed to prevent water leaks through the discharge orifice of the valv

Check Valve with Removable Cover

Description The NR-040 series Swing-Type Check Valve allows for one-directional flow and prevents the return flow of the liquid to its source.The check valve is designed with a removable top cover which allows for cleaning and maintenance of the check valve without the need to remove it from the pipeline.The disc is attached to the check valve body with the aid of an arm. The check valve seals with the closure of the disc against the sealing ring which is located at the opening of the check valve body.

Applications- Pump stations for potable water and wastewater- Filtration systems- Service line connections to the main line

Operation- Liquid flow through the check valve raises the disc to its open position and allows for the flow of liquids to the pipeline. - Two Possible Situations for Disc Closure

1. Regular quiet closure of the disc.2. Closure during the return flow of the water column, a situation that can cause slam of the disc and damage to the check valve.

- In order to prevent this destructive phenomenon, it is recommended to install a counterweight on the shaft of the check valve. With this addition, the disc will close at the point of water flow cessation and before the water column returns. The returning wave will impact on a closed disc and the acceleration of the disc closure will result in a minimal slam effect.- Another option is to install a hydraulic piston to control the closure of the disc.

Main Features- Maximum working temperature: 60° C.

Hydraulically Controlled Check ValveFull Hydraulic Transient Control

DescriptionThe A.R.I. Hydraulically Controlled Check Valve (HCCV) is a multipurpose damping device for pump discharge control. The valve functions as a one-directional Flow Control Valve, a Non-Return Valve and an internal Surge Anticipation Valve, all in one unit.The hydraulically controlled check valve consists of two major parts:1. A single shaft check valve. 2. A hydraulic control system.The hydraulic control system is mounted on the check valve and installed at the pump station. The HCCV hydraulically controls the opening and closing of the check valve disc. The valve prevents slam subsequent to pump shut-down, reduces water hammer while switching the pump on and off and alleviates surges resulting from a power failure at the pump station.

Applications - Pump Stations - at potable water, wastewater, desalination and industrial processing plants.

OperationThe HCCV consists of a self-contained unit operated both by the water flow generated by the main pump and by an electrically-powered hydraulic booster. The hydraulic control system manages the opening and closing phases of the check valve operation. The gradual opening phase is controlled at a predetermined rate. The angle and the timing of the two-stage closing phase can be adjusted to meet the flow regimen of the pipeline.

Main Features- Innovatively designed to specifically control surge.- The HCCV acts as an internal surge relief valve.- Damping characteristics can be synchronized to match the dynamic behavior of the surge waves in the system and can be adapted to the transient conditions in the pipeline.- Affords efficient pump station and pipeline protection.- Hydraulically-opened full flow passage greatly reduces head losses and lowers energy costs.- Controlled closing cycle remains fully functional, even during power failure.- Opening cycle of the A.R.I. HCCV is set to prevent surge at pump start-up.- Closing cycle of the A.R.I. HCCV is fully controlled and adjustable for the two principal phases:

1. Initial fast closing of the disk to 80% of its fully closed position – controllable from 2 to 10 seconds.2. Secondary, damping stage, from 80% to fully closed – controllable from 5 to 200 seconds.Supplemental fine-tuning by cam adjustments provides added flexibility of the operation.- Timing adjustments can be easily made on-site.- Smooth non-slam closure of the disc.- Face to face dimensions according to ISO and EN standards.- Metallic removable seals for easy servicing.- Sealing seats are corrosion and wear resistant.- Hydraulic accumulator provides the energy to close the disc in the event of a power failure.- Low maintenance, long working life.

Specifications- Nominal Size: 400 mm – 900 mm- Pressure Rating: 6 bar, 10 bar, 16 bar.- Max. Working Temp.: 70°C- Electric Oil Pump: 3 Phase - 220 V, 5HP- Electric Power Control: 24 DVC

Options- Higher back-pressure application.- Horizontal or Vertical Installation, upon request - for confined spaces.- Special internal/external coatings for use with corrosive liquids.

Do not force parts to fit.

RP-500 PN 10

Backflow Preventer

Description The RP-500 Backflow Preventer is designed to supply maximum protection against backflow caused by negative pressure or backpressure. Backflow may cause infiltration of chemicals, fertilizers and/or other pollutants into potable water systems. The RP-500 is reliable and easily maintained, without the need for special tools. The RP-500 is built with two independent, easily replaceable capsulated spring-loaded check valves. A revolutionary, internal Reduced Pressure Zone, located between the check valves, ensures protection and reliable performance of the relief valve.

Applications - Chemical and fertilizer systems in landscape and agriculture.- Swimming pools- Dairies and poultry coops

Operation During normal flow, the two check valves open to supply water downstream. The Relief Valve is power-activated by upstream pressure and is kept shut by a diaphragm, through the internal control system. In the zone, the area between the check valves, pressure is maintained at approximately 0.43 bar lower than the water supply pressure. The Outlet Check Valve is spring-loaded to maintain a minimum pressure decrease of 0.07 bar. When negative pressure or sub-atmospheric conditions occur, the Inlet Check Valve closes to prevent backflow. If the Outlet Check Valve fails, the pressure between the two check valves rises, opening the Relief Valve and releasing the water to the atmosphere. The Relief Valve operates on differential pressure. Supply pressure on the upstream side of the Inlet Check Valve acts against the diaphragm to close the Relief Valve during normal operation. In the event of backpressure or backsiphonage, the Relief Valve will open to maintain the pressure in the “zone” at 0.14 bar less than the inlet pressure.

Note: If water continues to drain from the Relief Valve, check the Troubleshooting section for probable causes and solutions.

Main Features, Advantages and Benefits - Working Pressure: 10 bar. - Sizes: 1/2”, 3/4”, 1”,1 ¼”, 1 ½”, 2”. - Temp: 0.5° to 45° C. - Made of composite plastic material: resistant to corrosion, scaling, fertilizers, herbicides, insecticides, etc.

Unmeasured-Flow Reducer PATENTED

Apparent (commercial) water lossesA major cause for apparent water losses is the fact that domesticwater meters have difficulty in measuring very low flow ratesmainly below Qmin.The minimum flow rate (Qmin), where an accuracy of +/–5% isrequired by the appropriate ISO standard for small domesticwater meters (Qn 1.5), is 30 l/h for class B water meters, 15 l/hfor class C water meters and 11.25 l/h for class D water meters.

Loss of income due to the under-registration of watermeters at low flow ratesUnder-registration of low flow rates is the main reason forapparent water losses and it can account for 5%-10% of thetotal water sold to users by the water utility. For old watermeters, where the measuring starting point is higher and for houseswith water storage tanks, apparent water losses can be more than10%.

Main reasons for leaks and low flow rates that causeunder-registration of the water meter:- Dripping or improperly closed faucet.- Leaks in toilet tank seals.- Very low flow rates at the end of the filling cycle of toilet tanksand water storage tanks.- Pipework leaks downstream of the water meter.

A.R.I.’s Solution: UFR - Unmeasured-Flow ReducerUFR - Is a smart and simple product, installed in the domesticwater supply line (In-Line), adjacent to the water meter.UFR - At low flow rates, changes the flow regime to batchesthat the water meter can measure.

UFR - Operating PrinciplesThe UFR begins working at very low flow rates, below Qmin.The UFR regulates the water flow so there is no water flowat all through the UFR part of the time, while the rest of thetime, the flow is high enough to be measured. A change in theflow discipline at low flow rates allows the existing water meterto measure those low flow rates it could not measure before.When the flow rate increases above Qmin, the UFR remainsopen, so that it does not interfere with normal measurements.

Advantages of the UFR- Reduces unmeasured flow, cuts down apparent losses.- Substantially increases the income of the water utility, upto 10%.- The UFR is a high quality check valve preventing backflowand main pipe contamination.- When water is billed in a block of flats according to the domesticwater meter plus the mean difference between the domesticwater meters and the main water meter, the UFR can make thebilling fairer.- Turns apparent water losses into revenue water.- Reduces measurement differences between the main watermeter and domestic water meters.- Helps detect small leaks downstream of the water meter.

The A.R.I. UFR is approved by the following Standardsauthorities:WRAS, PZH, The Standards Institution of ISRAEL.

How Does The UFR Work:

1. UFR closedWhen pressure on both sides of the UFR is equal, the spring pushes the plunger to the “closed” position.

2. UFR starts openingLeakage causes the downstream pressure to decrease - and the plunger moves forward, pulling the rubber seal with it.

3. UFR opensThe plunger seal disengages instantaneously and the water batch moves quickly forward and activates the water meter.

4. UFR closes againWhen pressure on both sides of the UFR is equal the spring pushes the plunger back to the "closed" position.

Combination Air Valve for Wastewater

DescriptionThe D-020 Combination Air Valve combines an air & vacuum orifice and an air release orifice in a single body. The valve is specially designed to operate with liquids carrying solid particles such as wastewater and effluents. The combination air valve discharges air (gases) during the filling or charging of the system, admits air into the system while it is being emptied of liquid and releases accumulated air (gases) from the system while it is under pressure and operating. The valve’s unique design enables the separation of the liquid from the sealing mechanism and assures optimum working conditions.

Applications -Pump stations for sewage, wastewater & water treatment plants. -Wastewater, effluent water and sea water supply lines.

OperationThe air & vacuum component discharges air at high flow rates during the filling of the system and admits air into the system at high flow rates during its drainage and at water column separation.High velocity air will not blow the float shut. Water will lift the float which seals the valve.At any time during system operation, should internal pressure of the system fall below atmospheric pressure, air will enter the system.The smooth discharge of air reduces pressure surges and other destructive phenomena.The intake of air in response to negative pressure protects the system from destructive vacuum conditions and prevents damage caused by water column separation. Air entry is essential to efficiently drain the system.The air release component releases entrapped air in pressurized systems.

Without air valves, pockets of accumulated air may cause the following hydraulic disturbances:- Restriction of effective flow due to a throttling effect as would a partially closed valve. In extreme cases this will cause complete flow stoppage.- Obstruction of efficient hydraulic transmission due to air flow disturbances.- Accelerate cavitation damages.- Pressure transients and surges.- Corrosion in pipes, fittings and accessories.- Danger of a high-energy burst of compressed air.- Inaccuracies in flow metering.

As the system starts to fill, the combination wastewater valve functions according to the following stages: 1. Entrapped air/gas is discharged by the valve 2. When the liquid level reaches the valve’s lower portion, the lower float is lifted, pushing the sealing mechanism to its sealing position. 3. The entrapped air is confined in a pocket between the liquid and the sealing mechanism. The air pressure is equal to the system pressure. 4. Increases in system pressure compress the trapped air in the upper section of the conical chamber. The conical shape assures the height of the air gap. This enables separation of the liquid from the sealing mechanism. 5. Entrapped air (gas), accumulating at peaks and along the system, rises to the top of the valve, and displaces the liquid in the valve’s body. 6. When the liquid level is lowered to a point where the float is no longer buoyant, the float drops, unsealing the rolling seal. The air release orifice opens and allows part of the air that accumulated in the upper portion of the valve to be released to the atmosphere. 7. Liquid enters the valve. The float rises, pushing the rolling seal to its sealing position. The remaining air gap prevents the wastewater from fouling the mechanism.

When internal pressure falls below atmospheric pressure (negative pressure): 1. The floats will immediately drop down, opening the air & vacuum and air release orifices.2. Air will enter the system.

Main Features- Working pressure range: 0.2 - 16 bar. - Testing pressure: 25 bar. - Maximum working temperature: 60° C. - Maximum intermittent temperature: 90° C.- The unique design of the valve prevents contact between the wastewater and the sealing mechanism by creating an air gap at the top of the valve. These features are achieved by: • The conical body shape: designed to maintain the maximum distance between the liquid and the sealing mechanism and still obtain minimum body length. • Spring-loaded joint between the stem and the upper float: vibrations of the lower float will not unseal the air release component. Release of air will occur only after enough air accumulates. • The Rolling Seal Mechanism: less sensitive to pressure differentials than a direct float seal. It accomplishes this by having a

EnC-D

020SWG

-11 159

comparably large orifice for a wide pressure range (up to 16 bar). • Funnel-shaped lower body: designed to ensure that residue wastewater matter will fall back into the system and be carried away by the main pipe. - All inner metal parts made of stainless steel. - 1½" threaded discharge outlet enables removal of excess fluids. - Dynamic design allows for high velocity air discharge while preventing premature closure.- 1" ball valve releases trapped pressure and drains the valve body prior to maintenance.

Valve Selection- Size range 2" – 8".- These valves are manufactured with flanged ends to meet any requested standard - The 2” valve is also available with a threaded BSP or NPT connection. - Standard metal body, also available with a stainless steel body. - Valve body coating: fusion bonded epoxy coating according to the standard DIN 30677-2.- Other coatings are available upon request.- Additional accessories:• With a One-way, Out-only attachment, allows for air discharge only, prevents air intake. • With a Vacuum Breaker, In-only attachment, allows for air intake only, prevents air discharge. • With a Non-Slam discharge-throttling attachment, allows for free air intake, throttles air discharge.

Note- The D-020 air valve is intended for use with raw wastewater. For use with aggressive liquids, please consult with our application engineers or with the marketing dept.- For best suitability, it is recommended to send the fluid chemical properties along with the valve request. - Upon ordering, please specify: model, size, working pressure, threads standard and type of liquid.

Underground Air Valve System for Wastewater

Description The D-020 SB is a complete product package that combines the reliable and efficient properties of the A.R.I. D-020 combination wastewater air valve with the added feature of a sub-surface valve that can be buried below ground. A specially designed gear box operated horizontal sliding disc valve - situated at the base of the D-020 SB assembly - allows for the air valve disconnection and maintenance from ground level. This shut-off valve is equipped with a safety mechanism enabling disconnection and removal of the D-020 air valve from its subsurface housing, even when the system is under pressure. Since service and maintenance operations of the unit are performed entirely from the surface, there is no need for safety considerations associated with confined space entry. The D-020 Combination Air Valve combines an air & vacuum orifice and an air release orifice in a single body. The valve is specially designed to operate with liquids carrying solid particles such as wastewater and effluents. The combination air valve discharges air (gases) during the filling or charging of the system, admits air into the system while it is being emptied of liquid and releases accumulated air (gases) from the system while it is under pressure and operating. The valve’s unique design enables the separation of the liquid from the sealing mechanism and assures optimum working conditions.

Applications - Pump stations for sewage, wastewater & water treatment plants. - Wastewater, effluent water and sea water supply lines.


Without air valves, pockets of accumulated and entrained air may cause the following hydraulic disturbances:- Restriction of effective flow due to a throttling effect as would a partially closed valve. In extreme cases this will cause complete flow stoppage.- Obstruction of efficient hydraulic transmission due to air flow disturbances.- Accelerate cavitation damages.- Pressure transients and surges.- Corrosion in pipes, fittings and accessories.- Danger of high-energy bursts of compressed air.- Inaccuracies in flow metering.

D-023 PN 16

Combination Air Valve for Wastewater PATENTED

Description The D-023 Combination Air Valve combines an air & vacuum orifice and an air release orifice in a single body. The valve is specially designed to operate with liquids carrying solid particles such as wastewater and effluents. The combination air valve discharges air (gases) during the filling or charging of the system, admits air into the system while it is being emptied of liquid and releases accumulated air (gases) from the system while it is under pressure and operating. The valve’s unique design enables the separation of the liquid from the sealing mechanism and assures optimum working conditions.

Applications - Pump stations for sewage, waste water & water treatment plants. - Wastewater, effluent water and sea water supply lines.

Operation The air & vacuum component discharges air at high flow rates during the filling of the system and admits air into the system at high flow rates during its drainage and at water column separation.High velocity air will not blow the float shut. Water will lift the float which seals the valve.At any time during system operation, should internal pressure of the system fall below atmospheric pressure, air will enter the system.The smooth discharge of air reduces pressure surges and other destructive phenomena.The intake of air in response to negative pressure protects the system from destructive vacuum conditions and prevents damage caused by water column separation. Air entry is essential to efficiently drain the system.The automatic air release component releases entrapped air in pressurized systems.


As the system starts to fill, the combination wastewater valve functions according to the following stages: 1.Entrapped air/gas is discharged by the valve 2. When the liquid level reaches the valve’s lower portion, the lower float is lifted, pushing the sealing mechanism to its sealing position. 3. The entrapped air is confined in a pocket between the liquid and the sealing mechanism. The air pressure is equal to the system pressure. 4. Increases in system pressure compress the trapped air in the upper section of the conical chamber. The conical shape assures the height of the air gap. This enables separation of the liquid from the sealing mechanism. 5. Entrapped air (gas), accumulating at peaks and along the system, rises to the top of the valve, and displaces the liquid in the valve’s body. 6. When the liquid level is lowered to a point where the float is no longer buoyant, the float drops, unsealing the rolling seal. The air release orifice opens and allows part of the air that accumulated in the upper portion of the valve to be released to the atmosphere. 7. Liquid enters the valve. The float rises, pushing the rolling seal to its sealing position. The remaining air gap prevents the wastewater from fouling the mechanism. When internal pressure falls below atmospheric pressure (negative pressure): 1. The floats will immediately drop down, opening the air & vacuum and air release orifices.2. Air will enter the system.

Main Features - Working pressure range: 0.2 - 16 bar. - Testing pressure: 25 bar. - Maximum working temperature: 60° C. - Maximum intermittent temperature: 90° C.- The unique design of the valve prevents contact between the wastewater and the sealing mechanism by creating an air gap at the top of the valve. These features are achieved by: • The conical body shape and the external lever: designed to maintain the maximum distance between the liquid and the sealing mechanism and still obtain minimum body length. • Spring loaded joint between the stem and the upper float: vibrations of the lower float will not unseal the automatic valve. Release of air will occur only after enough air accumulates. • Funnel-shaped lower body: designed to ensure that residue wastewater matter will fall back into the system and be carried away by the main pipe. - All inner metal parts made of Stainless Steel.

The D-023 combination air valve for wastewater is available with an optional stainless steel two-directional discharge outlet cover. One outlet is always open for air discharge while the other is closed with a plug. Both outlets have a 3” female thread.With this option, air can be discharged either in a horizontal or vertical direction, depending on the installation. This option allows for easy vertical air discharge from valves installed in manholes.This cover is standard on all D-023 SB underground air valves and is optional for all D-023 air valves, both stainless steel and epoxy coated.

The D-023 Combination Wastewater Non Slam accessory will dampen surge and prevent slam. The non slam accessory provides efficient surge suppression. At sudden drainage and/or water column separation (sudden pump trips or valve closure, for instance), the air & vacuum orifice admits air at high flow rates, thus preventing vacuum. As the water column and/or pressure wave returns, the large volumes of air are exhausted slowly through the smaller orifice of the non-slam acessory. This slowly exhausting air pocket dampens the slam of the returning water column, thus suppressing the pressure surge. As the water flow arrives at a much slower rate, dampened by the slower air discharge, it buoys up the main float, gently closing the air & vacuum component of the air valve.

Water will lift the float which seals the valve. At any time during system operation, should internal pressure of the system fall below atmospheric pressure, air will enter the system. The smooth discharge of air reduces pressure surges and other destructive phenomena.The intake of air in response to negative pressure protects the system from destructive vacuum conditions and prevents damage caused by water column separation.

Without air valves, pockets of accumulated air may cause the following hydraulic disturbances: - Restriction of effective flow due to a throttling effect as would a partially closed valve. In extreme cases this will cause complete flow stoppage.- Obstruction of efficient hydraulic transmission due to air flow disturbances.- Accelerate cavitation damages.- Pressure transients and surges.- Corrosion in pipes, fittings and accessories.- Danger of high-energy bursts of compressed air.- Inaccuracies in flow metering.

As the system starts to fill, the combination wastewater valve functions according to the following stages: 1. Entrapped air/gas is discharged by the valve 2. When the liquid level reaches the valve’s lower portion, the lower float is lifted, pushing the sealing mechanism to its sealing position. 3. The entrapped air is confined in a pocket between the liquid and the sealing mechanism. The air pressure is equal to the system pressure. 4. Increases in system pressure compress the trapped air in the upper section of the conical chamber. The conical shape assures the height of the air gap. This enables complete separation of the liquid from the sealing mechanism. 5. Entrapped air (gas), accumulating at peaks and along the system, rises to the top of the valve, and displaces the liquid in the valve’s body. 6. When the liquid level is lowered to a point where the float is no longer buoyant, the float drops, unsealing the rolling seal. The air release orifice opens and allows part of the air that accumulated in the upper portion of the valve to be released to the atmosphere. 7. Liquid enters the valve. The float rises, pushing the rolling seal to its

sealing position. The remaining air gap prevents the wastewater from fouling the mechanism.


Main Features - Working pressure range: 0.2 - 16 bar. - Maximum working temperature: 60° C. - Maximum intermittent temperature: 90° C.- The unique design of the valve prevents contact between the wastewater and the sealing mechanism by creating an air gap at the top of the valve. These features are achieved by: • The conical body shape and the external rod: designed to maintain the maximum distance between the liquid and the sealing mechanism and still obtain minimum body length. • Spring loaded joint between the stem and the upper float: vibrations of the lower float will not unseal the automatic valve. Release of air will occur only after enough air accumulates. • Funnel-shaped lower body: designed to ensure that residue wastewater matter will fall back into the system and be carried away by the main pipe.• The Rolling Seal Mechanism: less sensitive to pressure differentials than a direct float seal. It accomplishes this by having a comparably large orifice for a wide pressure range (up to 16 bar). - All inner metal parts made of stainless steel. - Unique design prevents contact between the wastewater and the sealing mechanism, prevents clogging by floating solids and ensures drip-tight sealing. - The D-026 orifice plug-disc linkage assembly is external, keeping the rod and pins outside the air valve body and its corrosive atmosphere. - Discharge outlet enables removal of excess fluids- 1” ball valve releases trapped pressure and drains the valve body prior to maintenance.

Valve Selection - Size availability: 6”, 8”. - Valve manufactured with flanged ends to meet any requested standard.- Valve body coating: fusion bonded epoxy coating according to the standard DIN 30677-2.- Standard metal body and polyethylene cover, also available with a ST. ST. body and polyethylene cover.- An optional Non-Slam discharge-throttling attachment (see drawing on next page), allows for free air intake, throttles air discharge.- Additional coatings including Halar are available upon request.

G-11 189

Description The K-020 & K-022 Air & Vacuum Valves are specially designedto operate with liquids carrying solid particles such as wastewaterand effluents. These air & vacuum valves discharge air (gases) duringthe filling or charging of the system and admit air into the systemwhile it is being emptied of liquid. The valve’s unique design enablesthe separation of the liquid from the sealing mechanism and assuresoptimum working conditions.

Applications -Pump stations for sewage, wastewater & water treatment plants.-Wastewater, effluent water and sea water supply lines. OperationThe K-020 & K-022 air & vacuum valves discharge air at high flowrates during the filling of the system and admit air into the system athigh flow rates during its drainage and at water column separation.High velocity air will not blow the float shut. Water will lift thefloat which seals the valve.At any time during system operation, should internal pressure of thesystem fall below atmospheric pressure, air will enter the system.The smooth discharge of air reduces pressure surges and otherdestructive phenomena.The intake of air in response to negative pressure protects the systemfrom destructive vacuum conditions and prevents damage caused bywater column separation. Air entry is essential to efficiently drainthe system.

As the system starts to fill, the valve functions according to thefollowing stages:1. Entrapped air/gas is discharged by the valve 2. When the liquid level reaches the valve’s lower portion, the float islifted, pushing the sealing mechanism to its sealing position.

When internal pressure falls below atmospheric pressure (negativepressure):1. The floats will immediately drop down, opening the air & vacuumorifice.2. Air will enter the system.

Main Features - Working pressure range: K-020 0.2 - 16 bar. K-022 0.2 - 25 bar- Testing Pressure: 1.5 times the working pressure of the air valve.- Maximum working temperature: 60° C.- Maximum intermittent temperature: 90° C.- The valve’s unique design prevents contact between the wastewater and the sealing mechanism by creating an air gap at the top of thevalve. Those features are achieved by:• The conical body shape: designed to maintain the maximum distance between the liquid and the sealing mechanism and still obtain minimum body length.• Funnel-shaped lower body: designed to ensure that residue wastewater matter will fall back into the system and be carried away by the main pipe.-Flushing is possible while the valve is under pressure by opening theball valve in the valve’s lower part. Valve Selection- Size range: 3” - 4”.- These valves are manufactured with flanged ends to meet any requested standard.- Standard metal body, also available with a stainless steel body.- Air valve coating: fusion bonded epoxy according to standardDIN 30677-2.- Other coatings are available upon request.- Optional Accessories• With a One-Way, Out-only attachment, allows for air discharge only, prevents air intake.• With a Vacuum Breaker, In-only attachment, allows for air intakeonly, prevents air discharge.• With a Non-Slam discharge-throttling attachment, allows for freeair intake, throttles air discharge.

Automatic Air Release Valve for Wastewater

Description The S-020 and S-022 Automatic Air Release Valves are specially designed to operate with liquids carrying solid particles such as wastewater and effluent.The valves release accumulated air (gases) from the system while under pressure and operating. The valve’s unique design enables the separation of the liquid from the sealing mechanism and assures optimum working conditions.The presence of air in a wastewater system can reduce the effective cross sectional flow area, resulting in increased head loss and decreased flow.Unwanted air may also cause water hammer and metering inaccuracies, while hastening corrosion.


Operation A.R.I. models S-020, S-022 are air release valves for wastewater systems. As the system starts to fill, the automatic air release valve functions according to the following stages: 1. When the liquid level reaches the valve’s lower portion, the lower float is lifted, pushing the sealing mechanism to its sealing position. 2. The entrapped air is confined in a pocket between the liquid and the sealing mechanism. The air pressure is equal to the system pressure. 3. Increases in system pressure compress the trapped air in the upper section of the conical chamber. The conical shape assures the height of the air gap. This enables separation of the liquid from the sealing mechanism. 4. Entrapped air (gas), accumulating at peaks and along the system, rises to the top of the valve, and displaces the liquid in the valve’s body. 5. When the liquid level is lowered to a point where the float is no longer buoyant, the float drops, unsealing the rolling seal. The air release orifice opens and allows part of the air that accumulated in the upper portion of the valve to be released to the atmosphere. 6. Liquid enters the valve. The float rises, pushing the rolling seal to its sealing position. The remaining air gap prevents the wastewater from fouling the mechanism. Note: Automatic air release valves are designed to release air as it accumulates at peaks in pressurized systems. They are not normally recommended for vacuum protection or for discharging large volumes of air, because of their inherently small orifices. For this

purpose, air & vacuum valves are recommended as they have much larger orifices.However, air release valves will permit air to enter the system under vacuum conditions. If this is not desirable, specify the one-way out check valve.

Main Features - Working pressure range: S-020 0.2 - 16 bar, S-022 0.2 - 25 bar - Testing pressure: S-020 25 bar, S-022 40 bar - Maximum working temperature: 60° C. - Maximum intermittent temperature: 90° C.- The unique design of the valve prevents contact between the wastewater and the sealing mechanism by creating an air gap at the top of the valve. These features are achieved by: • The conical body shape: designed to maintain the maximum distance between the liquid and the sealing mechanism and still obtain minimum body length.• Spring-loaded joint between the stem and the upper float: vibrations of the lower float will not unseal the air release component. Release of air will occur only after enough air accumulates. • Funnel-shaped lower body: designed to ensure that residue wastewater matter will fall back into the system and be carried away by the main pipe. • Rolling seal: provides smooth positive opening, closing, and leak free sealing over a wide range of pressure differentials. - Internal metal parts: made of corrosion resistant stainless steel. - Threaded discharge outlet enables removal of excess fluids.- 1” ball valve releases trapped pressure and drains the valve body prior to maintenance.

Valve Selection- Size range: 2”– 4”.- These valves are manufactured with flanged ends to meet any requested standard - The 2” valve is also available with a BSP or NPT male threaded connection. - Standard metal body, also available with a stainless steel body. - Valve body coating: fusion bonded epoxy coating according to the standard DIN 30677-2.- Other coatings are available upon request.- Available in S-020 - PN16, S-022 - PN25.

Automatic Air Release Valve for Reclaimed and Non-Potable Water

DescriptionThe S-021 Automatic Air Release Valve is specially designed to operate with liquids carrying solid particles.The automatic air release valve releases accumulated air from the system while it is under pressure.The valve’s unique design enables the separation of the liquid from the sealing mechanism and assures optimum working conditions. The presence of air in a reclaimed and non-potable water system can reduce the effective cross sectional flow area, resulting in increased head loss and decreased flow.Unwanted air may also cause water hammer and metering inaccuracies, while hastening corrosion.


OperationThe S-021 is an air release valve for reclaimed and non-potable water systems. As the system starts to fill, the automatic air release valve functions according to the following stages: 1. When the liquid level reaches the valve’s lower portion, the lower float is lifted, pushing the sealing mechanism to its sealing position. 2. The entrapped air is confined in a pocket between the liquid and the sealing mechanism. The air pressure is equal to the system pressure. 3. Increases in system pressure compress the trapped air in the upper section of the conical chamber. The conical shape assures the height of the air gap. This enables separation of the liquid from the sealing mechanism. 4. Entrapped air (gas), accumulating at peaks and along the system, rises to the top of the valve, and displaces the liquid in the valve’s body. 5. When the liquid level is lowered to a point where the float is no longer buoyant, the float drops, unsealing the rolling seal. The air release orifice opens and allows part of the air that accumulated in the upper portion of the valve to be released to the atmosphere. 6. Liquid enters the valve. The float rises, pushing the rolling seal to its sealing position. The remaining air gap prevents the wastewater from fouling the mechanism.

Note: the automatic air valves are specifically designed to release air as it accumulates at the high points of a pressurized, operating system. Because of their inherently small orifice size, they are not recommended for vacuum protection or for discharging large quantities of air or gas, although they will admit some air into the system under vacuum conditions.

Main Features- Working pressure range: 0.2 - 10 bar - Testing pressure: 16 bar - Maximum working temperature: 60° C. - Maximum intermittent temperature: 90° C.- Body made of composite plastic material, resistant to corrosion.- Internal metal parts are made of corrosion-resistant stainless steel.- Floats are made of composite materials.- Flexible rolling seal provides smooth positive opening, closing, and leak-free sealing over a wide range of pressure differentials.- 1/8” threaded discharge outlet enables removal of excess fluids.- Drainage tap with ball valve is provided.- The unique design of the valve prevents contact between the wastewater and the sealing mechanism by creating an air gap at the top of the valve. These features are achieved by: • The conical body shape: designed to maintain the maximum distance between the liquid and the sealing mechanism and still obtain minimum body length. • Funnel-shaped lower body: designed to ensure that residue wastewater matter will fall back into the system and be carried away by the main pipe. • Rolling Seal: provides smooth positive opening, closing, and leak- free sealing over a wide range of pressure differentials. - 1/4” ball valve releases trapped pressure and drains the valve body prior to maintenance.

Valve Selection- Size Range: 1”& 2”, BSP or NPT male threaded connection or flanged to meet any requested standard.- Flanges are manufactured of composite materials.- Additional one-way out check valve attachment allows air discharge, not allowing air intake.- For best suitability, it is recommended to send the fluid chemical properties along with the valve request.

S-025-SB PN 10


Description The S-025 SB is a complete product package that combines the reliable and efficient properties of the A.R.I. S-025 automatic air release wastewater valve with the added feature of a sub-surface valve that can be buried below ground. A specially designed gear box operated horizontal sliding disc valve - situated at the base of the S-025 SB assembly - allows for the air valve disconnection and maintenance from ground level. This gear box operated shut-off valve is equipped with a safety mechanism enabling disconnection and removal of the S-025 air valve from its subsurface housing, even when the system is under pressure. Since service and maintenance operations of the unit are performed entirely from the surface, there is no need for safety considerations associated with confined space entry.The S-025 Automatic Air Release Valves are specially designed to operate with liquids carrying solid particles such as wastewater and effluent. The valves release accumulated air (gases) from the system while under pressure and operating. The valve’s unique design enables the separation of the liquid from the sealing mechanism and assures optimum working conditions.

Applications - Underground municipal and industrial wastewater and effluent pressurized pipelines.- Underground pressurized pipelines conveying liquids with suspended solids and grime.

OperationAs the system starts to fill, the automatic air release valve functions according to the following stages: 1. When the liquid level reaches the valve’s lower portion, the lower float is lifted, pushing the sealing mechanism to its sealing position. 2. The entrapped air is confined in a pocket between the liquid and the sealing mechanism. The air pressure is equal to the system pressure. 3. Increases in system pressure compress the trapped air in the upper section of the conical chamber. The conical shape assures the height of the air gap. This enables separation of the liquid from the sealing mechanism. 4. Entrapped air (gas), accumulating at peaks and along the system, rises to the top of the valve and displaces the liquid in the valve’s body. 5. When the liquid level is lowered to a point where the float is no longer buoyant, the float drops, unsealing the rolling seal. The air release orifice opens and allows part of the air that accumulated in the upper portion of the valve to be released to the atmosphere.

6. Liquid enters the valve. The float rises, pushing the rolling seal to its sealing position. The remaining air gap prevents the wastewater from fouling the mechanism. Note: Automatic air release valves are designed to release air as it accumulates at peaks in pressurized systems. They are not normally recommended for vacuum protection or for discharging large volumes of air, because of their inherently small orifices. For this purpose, air & vacuum valves are recommended as they have much larger orifices.However, air release valves will permit air to enter the system under vacuum conditions. If this is not desirable, specify the one-way out check valve.

These features are achieved by:1. The conical body shape: designed to maintain the maximum distance between the liquid and the sealing mechanism and still obtain minimum body length.2. Spring-loaded joint between the stem and the upper float: vibrations of the lower float will not unseal the air release component. Release of air will occur only after enough air accumulates.3. The Rolling Seal mechanism: less sensitive to pressure differentials than a direct float seal. It accomplishes this by having a comparably large orifice for a wide pressure range (up to 10 bar).4. Funnel-shaped lower body: designed to ensure that residue wastewater matter will fall back into the system and be carried away by the main pipe.

DescriptionA.R.I. model SD-010GB is a 3" inlet, gear box driven horizontal sliding disc valve designed for underground and confined space installations. The gear box is activated by a vertical operating rod (enables above ground operation of underground installations). The valve provides fluid-tight sealing up to 25 bar (365 psi) working pressure and is installed horizontally between the pipeline and the user's device. Integral to the valve is either a 2" or 3" threaded or quick connection adaptor outlet. The 3" adaptor has an additional 1 ½" BSP female threaded orifice perpendicular to its vertical access, which can be used as a flushing outlet. The quick connection adaptor has a built in safety mechanism to prevent the accidental removal of the user's device while there is open flow through the valve. The disc valve must be in the closed position before the user's device can be disconnected from the quick connection adaptor.

Applications - Underground installations of air valves. - Installation of air valves and valves in confined spaces. - Fire hydrants. - Municipal services.- Wastewater manholes.

Operation The valves’ unique design allows for operation from above, thus enabling its use in underground and confined space applications.

Check Valve with Removable Cover

Description The NR-040 series Swing-Type Check Valve allows for one-directional flow and prevents the return flow of the liquid to its source.The check valve is designed with a removable top cover which allows for cleaning and maintenance of the check valve without the need to remove it from the pipeline.The disc is attached to the check valve body with the aid of an arm. The check valve seals with the closure of the disc against the sealing ring which is located at the opening of the check valve body.

Applications- Pump stations for potable water and wastewater- Filtration systems- Service line connections to the main line

Operation- Liquid flow through the check valve raises the disc to its open position and allows for the flow of liquids to the pipeline. - Two Possible Situations for Disc Closure

1. Regular quiet closure of the disc.2. Closure during the return flow of the water column, a situation that can cause slam of the disc and damage to the check valve.

- In order to prevent this destructive phenomenon, it is recommended to install a counterweight on the shaft of the check valve. With this addition, the disc will close at the point of water flow cessation and before the water column returns. The returning wave will impact on a closed disc and the acceleration of the disc closure will result in a minimal slam effect.- Another option is to install a hydraulic piston to control the closure of the disc.

Main Features- Maximum working temperature: 60° C. - Maximum intermittent temperature: 90° C.- Surge-resistant cast iron body. - Bronze or ductile iron disc with natural rubber flap seal, seals at low pressures and eliminates wear and tear of the flap. - Corrosion-resistant inner parts ensure long term service under adverse conditions.

Control and Effect of Air in Irrigation SystemsAir in an irrigation system must be controlled because the presence of air bubbles and air pockets, or their absence (vacuum), can cause problems and damage to the system.

Problems and Damage Caused by the Presence of Air Pockets and Air Bubbles in Water Pipelines1. Uneven flow through the pipe – sometimes even stopping water flow altogether.2. High losses of water head and consequently, energy losses.3. Water hammer damage to the pipes, accessories and connectors.4. False readings of water meters and automatic metering devices (and consequent payment for water not supplied, virtual use of water above licensed pumping limits, under utilization of available water supplies, inadequate supply of water to crops because plants receive less water than the volume measured by the hydrometer or water meter). 5. Inadequate supply of water to agricultural crops caused by throttling of flows and accumulated pressure losses at system ends. 6. Extensive damage to impeller systems in water meters, hydrometers, sprinklers and sprayers. 7. Corrosion damage.8. Physical risk - when large volumes of air are released at high velocity.

The Problems Exacerbated by the Presence of a Vacuum1. Mud and dirt are sucked into the system through drippers. 2. Seals, drippers and other accessories are sucked into the main distribution lines.3. Uncontrolled entry of chemicals and fertilizers injected into agricultural and landscape irrigation systems.4. Vacuum-induced collapse of pipes and accessories (sub-atmospheric pressures).5. Increased risk of surge and slam conditions during the release of air pockets. 6. Cavitation damages..

Control of Air in Irrigation Systems Using A.R.I. Air ValvesThere are three main types of air valves installed in irrigation systems: air & vacuum, automatic air release and combination (double) valves. Air & Vacuum valves discharge large quantities of air from non-pressurized pipes and are used mainly when filling a line. These valves also make it possible to admit large quantities of air when lines are drained and at water column separation. Air & Vacuum valves are also known as: kinetic valves; large orifice air valves, vacuum breakers, low-pressure air valves and air-relief valves.

Automatic air release valves continuously release relatively small quantities of air from a pressurized line. The automatic air valve is also known as an: air release valve; small orifice air valve and as a pressure air valve.

Combination air valves fulfill the tasks required of both types of valve – air & vacuum and automatic. In other words – they discharge or admit large volumes of air when filling or emptying a system and continuously release small volumes air when the line is pressurized. Combination air valves are also known as double orifice air valves.

The Range of Advanced Air Valves from A.R.I. Flow Control AccessoriesA.R.I. is one of the world’s leading manufacturers of air valves. A.R.I. engineers have developed a range of advanced composite material air valves, specially designed for use in agricultural and landscaping applications. Technologically, the product range is based on the A.R.I. patented rolling seal mechanism, which replaces the old system that uses the valve float to seal air valve orifices. The rolling seal mechanism and the aerodynamically designed float, in this line of air valves, provide much greater efficiency (larger orifices) and have better resilience to withstand dynamic valve closure. The new sealing mechanism enabled the development of small, lightweight air valves with a superior cost / benefit ratio. The width of the SG-10 automatic air valve from A.R.I. is a mere 87 millimeters; it stands no more than 140 mm high and weighs just 330 grams. Despite its small dimensions, the area of air orifice in this valve reaches 12 mm, which permits the release of 152 cubic meters of air per hour and can withstand pressures of up to 10 bar. The valve's integral self-cleaning mechanism prevents blockages, leaks and particles from sticking to the sealing faces.

The DG-10 model valve is just 180 mm wide, (including the protruding drainage funnel) 209 mm tall and weighs only 1.1 kg. With 12mm of automatic orifice area and 804 mm of kinetic orifice area, intake and release of air is very efficient – even more efficient than much larger and much heavier air valves, which are overwhelmed and slam closed at lower differential pressures. The valve's integral self-cleaning mechanism prevents blockages and leaks and particles do not stick to the sealing faces.

The R&D team at A.R.I has also developed the AV-010 air & vacuum valve to provide solutions for agricultural and landscaping irrigation systems. The product is manufactured from composite materials and is available in 3”, 2”, 1” and 3/4” sizes. It is lightweight, compact and very competitively priced.

RECOMMENDATIONS

Calculating the Number of Valves Required for Installation at Different Points in a System Most irrigation systems on individual farms have relatively uncomplicated conditions and decisions can be based on the following table:

To calculate the number of DG-10 (Barak) air valves required in an irrigation system, two criteria must be considered:- The need to protect against vacuum damage (achieved by admitting air into the system)- The need to discharge air from the system when it is filled with water

Air discharge requirements are usually lower than the air intake requirements for a line because the rates at which lines can be filled are generally lower. Diagram Number 1 can be used to establish air discharge requirements during line filling. In Diagram Number 1, it can be seen that one DG-10 valve is enough for pipes with a diameter of up to 8” (and sometimes up to 10”).This diagram is based on the release of air with a differential pressure of 0.4 bar.

The number of 2” DG-10 air valves required during the filling of a line according to line filling rate (with a pressure differential of 0.4 Bar) and pipe diameter.

Vacuum protection demands are usually higher, and this is particularly true when the line has acute angles of ascent and descent and / or when the pipe has a large diameter. Diagram Number 2 is based on the Hazen – Williams friction loss equation; a Hazen – Williams coefficient of 110 and a negative pressure differential of 0.4 bar.

The number of 2” DG-10 air valves required to protect against vacuum damage during line drainage according to pipe diameter and slopes of up to 15º (with a negative pressure differential of 0.4 Bar)

The number of 2” DG-10 air valves required during the filling of a line according to line filling rate (with a pressure differential of 0.4 Bar) and pipe diameter.

RECOMMENDATIONS

An Example of How to Evaluate The Size of Valves Required for Vacuum Prevention in a Dripper System with a Negative Pressure of 0.1 Bar.

Sample: At a slope of up to 10%, when air supply must reach 300 m3/hr.

Critical Velocity Required for Transporting Air Bubbles

At the point where the rate of water flow drops below the critical velocity for air movement, air valves should be located at these critical points. Installation of air valves is particularly important along long horizontal sections of line because flow rates are too low to carry air pockets and bubbles to the downstream air valves. Installation of air valves is also important on long descending sections of pipe in which the flow of water must overcome the opposing flow of air (flowing naturally to the high spots). See: Graphs describing critical speeds.

Calculating the Number of AV-010 Air & Vacuum Valves to be Installed in a Sub-surface Dripper System

An AV-010 air & vacuum valve, used to prevent vacuum conditions as low as a negative pressure of 1 m, must be installed in every sub-surface drip system to prevent suction of dirt into the drippers and subsequent blockages.An AV-010 air & vacuum valve must also be used to prevent the formation of a vacuum in dripper system laterals and thereby prevent their collapse. If the dripper-irrigated field is relatively flat and has no significant topographical changes, planning of air valve location will be based on the system’s working pressures and flow. If the dripper-irrigated field contains substantial topographic changes, calculation of the AV-010 air & vacuum valve numbers and locations will be based on the maximum drainage flow or on the flow of fluids during a burst the size of the pipe diameter, or the larger of the two

RECOMMENDATIONS

Characteristics of Water Systems Used in Agriculture and Landscaping:- High frequency changes in flow characteristics.- Water treatment in the field (filtration). - Chemicals and fertilizers are injected into the irrigation system.- Often necessary to use fragile and often complex equipment and instrumentation.- Large differences in the characteristics and materials used in pipes, connectors and accessories.

Installation at PumpsIt is recommended to install a DG-70 dynamic air valve directly after the pump and before the pump’s check valve. Water pumped from an independent supply such as a well, stream or reservoir requires the intake of air into the pump and suction pipes. This air will continue to disperse in the system during pump operation. Mode of Operation: When the pump begins operating, large volumes of air are discharged through the air & vacuum orifice of the air valve. The water flow raises the float, closes the orifice and opens the check valve. When the pump is shut down or ceases to operate for any other reason, air, admitted through the air & vacuum orifice, acts as a vacuum breaker. It protects the pump, connectors, accessories and seals from damage caused by sub-atmospheric (negative) pressure.The small automatic air release orifice continues to release air while the pump is working and the line is pressurized. At its location before the check valve, it protects the sealing face of the check valve from cavitation damage caused by the presence of small air bubbles in the water. It is recommended to install a SG-10 air valve on the pump to provide pump protection.It is recommended to install a DG-70 air valve after the pump check valve when the pipeline, upstream of this point, remains level or drops below ground level. This air valve will allow for the intake of air (at water column separation) when the pump is shut down and the check valve closes. It also will discharge air when the water column returns.

Installation in Locations with Changing Pressures It is recommended to install a 1” DG-10 air valve in areas with fluctuating pressure – pressure regulation valves, pressure release valves and at changes in pipe diameter. These are the areas where air pockets form and might migrate into the line. As the pipe is filled, these areas can become problematic if not provided with an adequate air release system. If pressure fluctuations are not too extreme, the SG-10 air valve will be sufficient when installed downstream and close to these sensitive areas (close to an accessory or disturbance).

Installation at the Highest Points in a LineIt is recommended to install a DG-10 air valve at all the highest points in each line where flow velocities drop below the critical velocity for air movement (See: Graphs section below). The air & vacuum component, installed at line high-points, discharges air as the line is filled and admits air during line drainage, regardless of whether the process is controlled or not (pipe burst or collapse).The automatic air release component releases air accumulating at high points when the line is pressurized during regular operations. Where the topography is relatively flat, the line has shallow slopes and the high points are relatively close, then the SG-10 automatic air release valve can replace the DG-10 valves at some of the high points.

INSTALLATION GUIDE

Installation on Long LinesOn long lines, it is recommended to install DG-10 or SG-10 valves every 500 meters to 800 meters. It is also recommended to install DG-10 valves on both sides of long sections of horizontal pipe.

Installation Close to a Main Line ValveWhen the line is pressurized and an isolating valve is closed, it is recommended to install an air valve before the isolating valve in order to release air. Installation of the air valve will protect the valve plate against cavitation damage caused by small air bubbles. During line fill, if a valve at the end of the line is closed, slowing down the filling process, it is recommended to install an air valve before the isolating valve on lines with large diameters and high flow rates. The installation of a DG-10 air valve after an isolating valve will also protect the line from negative pressure (vacuum) conditions caused when the valve is closed suddenly and assist in controlling the filling process when the isolating valve is open.

Installation Where a Line Crosses Under a Road or DitchIt is recommended to install a DG-10 air valve wherever a large diameter pipe, with sharp upward or downward angle changes, crosses under a road or ditch. When the crossing point is wide and/or deep, install the air valves at the uppermost point of the angle change on both sides of the road. If the crossing point is short and shallow, it is sometimes possible to install one DG-10 valve on the uppermost point of angle change on the downstream side of the crossing point.

Installation Before Water Meters and Automatic RegulatorsIt is recommended to install a DG-10 air valve on the upstream side of a flow meter and automatic flow regulator. Given that the water flow regulator is a special type of isolating valve, it is recommended to also install another DG-10 air valve on the downstream side after the regulator. Air can flow at velocities up to 29 times faster than water flow. The fast-moving flow of air through a water meter or through the unit that measures flow in the automatic regulator will spin the impeller, used to measure flow, at very high velocities These instruments, which cannot differentiate between water and air, will register very high flow volumes that do not, in fact, exist. Another problem created under such conditions is the inadequate supply of irrigation water to the fields caused by these air-related inaccurately recorded high flow rates. Water both cools and lubricates as it turns the impellers inside the measuring equipment. Air moving through the measuring unit at high speed causes the impeller to overheat and prevents water-cooling, resulting in high temperature damage that can even melt the plastic impeller. Installation of an air valve before the measuring equipment will protect the meter from heat damage and false readings.

Installation at the Main Line Control System It is recommended to install a combination DG-10 air valve directly on the vertical pipe at the main line control system. This will ensure control of air in the water supply and protection for the other accessories in the control system and protection for the water meters further downstream.Install an AV-010 “Guardian” model air valve after the tap on the lateral line feeding the dripper lines.

Installation on FiltersIt is recommended to install a DG-70 air valve on sand media filters and a DG-70 air valve on screen and disc filters.Filtering efficiency - air flowing through an automatic back flush filter system disrupts the filters’ hydraulic functioning, creating differential pressures in the filter. Consequently, the filter system flushes frequently, wasting water and lowering system efficiency.

If the lateral line is long, install a number of “Guardian” valves along the line, with emphasis on the highest points in the field and along the line. “Guardian” valves are required to prevent negative pressure (vacuum) in the line which can cause the drippers to suck up mud and dirt when flow stops.

Description The D-040 series Combination Air Valve has the features of both an air release valve and an air & vacuum valve.The air release component is designed to automatically release small pockets of air to the atmosphere as they accumulate at peaks or along a pipeline or piping system when it is full and operating under pressure.The air & vacuum component is designed to automatically discharge or admit large volumes of air during the filling or draining of a pipeline or piping system. This valve will open to relieve negative pressures whenever water column separation occurs.

Applications - Pump stations: after the pump and after the check valve.- On main lines and heads of systems.- At the end of lines and at the end of a sub main- On strainers and filters.

Operation

The air & vacuum component, with the large orifice, discharges air at high flow rates during the filling of the system and admits air into the system at high flow rates during its drainage and at water column separation.High velocity air will not blow the float shut. Water will lift the float, which seals the valve.At any time during system operation, should internal pressure of the system fall below atmospheric pressure, air will enter the system.The smooth discharge of air reduces pressure surges and other destructive phenomena.The intake of air in response to negative pressure protects the system from destructive vacuum conditions and prevents damage caused by water column separation. Air entry is essential to efficiently drain the system.The air release component releases entrapped air in pressurized systems.

Without air valves, pockets of accumulated air may cause the following hydraulic disturbances: - Restriction of effective flow due to a throttling effect as would a partially closed valve. In extreme cases this will cause complete flow stoppage.- Obstruction of efficient hydraulic transmission due to air flow disturbances.- Accelerate cavitation damages.- Pressure transients and surges.

- Corrosion in pipes, fittings and accessories.- Danger of a high-energy burst of compressed air.- Inaccuracies in flow metering.

As the system starts to fill, the valve functions according to the following stages:1. Entrapped air in the pipeline is discharged by the valve.2. Liquid enters the valve, lifting the float which pushes the sealing mechanism to its sealing position.3. Entrapped air, which accumulates at peaks and along the system, rises to the top of the valve, which in turn displaces the liquid in the valve’s body. 4. The float descends, unsealing the rolling seal. The air release orifice opens and the accumulated air is released.5. Liquid enters into the valve and the float rises, pushing the rolling seal back to its sealing position.


Main Features - Working pressure range: DG-10 0.1-10 bar. D-040 0.2-16 bar- Testing pressure: DG-10 16 bar. D-040 25 bar.- Maximum working temperature: 60° C. - Maximum intermittent temperature: 90° C.- Reliable operation reduces water hammer incidents.- Dynamic design allows for high velocity air discharge while preventing premature closure.- Lightweight, small dimensions, simple and reliable structure.- The discharge outlet enables removal of excess fluids.- The large size of the automatic air release orifice relative to the air valve body:• Discharges air at high flow rates.• Lessens the danger of its obstruction by debris.• Enables the usage of the patented rolling seal mechanism, making it less sensitive to pressure differential than a direct float seal.- The body is made of high-strength composite materials and all operating parts are made of specially selected, corrosion- resistant materials.- Due to its light weight, the valve may be installed on plastic piping systems, as well as other lightweight piping systems.

DG-70 PN 10


Description The DG-70 Dynamic Combination Air is a unique valve, operating without a float and utilizing the rolling diaphragm principle. This unique structure allows the dynamic air valve to discharge air from the water system in a controlled and gradual manner, thus preventing slam and local up-surges. When vacuum (down-surge) occurs, the valve reacts quickly to admit large volumes of air into the water system, thus impeding down-surges and, consequently, all pressure surges in the line. The air & vacuum component of the dynamic air valve is normally closed when the line is not operating, thus preventing the infiltration of debris and insects into the water system.

Applications Recommended installations: -Standard installation on water systems when the pipeline diameter is 8” or greater. -Installation on water systems for all pipeline diameters when the slope of the pipeline is greater than 2%-3%.

Operation When the system is charged and the pipeline begins to fill with water, air flows in the pipeline and enters into the dynamic air valve, raising the large orifice sealing assembly to the open position. Air isthen discharged, mainly out through the lower chamber large orifice as well as small amounts of air released out through upper chamber operating valve orifice. When the ensuing water enters the dynamic air valve, it fills the lower chamber and some of it flows up through the orifice chamber and enters into the upper operating chamber, raising the float of the operating valve which rolls the sealing mechanism to its sealed position. Pressure develops inside the upper operating chamber, bringing about a controlled lowering and sealing of the large orifice sealing assembly, which, in turn, closes the lower chamber large orifice.

NOTE: It is recommended to attach a drainage pipe to the connection on the large orifice outlet as some water will be expelled from the orifice during this closure stage. The size of the drainage pipe should be, at a minimum, the diameter of the outlet and the unattached end should remain open to the atmosphere.At this stage, only the automatic air release component continues to function and releases air through its small orifice. With a reduction in line pressure, during drainage or shut-off, the pressure in the valve is reduced and is lower then the outside atmospheric pressure.The vacuum created will cause the large orifice sealing assembly to rise up into its open position, opening the lower chamber large

Reclaimed Water

D-021 PN 10

Combination Air Valve - Reclaimed and Non-Potable Water

DescriptionThe D-021 Combination Air Valve combines an air & vacuum orifice and an air release orifice in a single body. The valve is specially designed to operate with liquids carrying solid particles such as reclaimed water and effluents. The combination air valve discharges air (gases) during the filling or charging of the system, admits air into the system while it is being emptied of liquid and releases accumulated air (gases) from the system while it is under pressure and operating. The valve’s unique design enables the separation of the liquid from the sealing mechanism and assures optimum working conditions.


OperationThe air & vacuum component discharges air at high flow rates during the filling of the system and admits air into the system at high flow rates during its drainage and at water column separation.High velocity air will not blow the float shut. Water will lift the float which seals the valve.At any time during system operation, should internal pressure of the system fall below atmospheric pressure, air will enter the system.The smooth discharge of air reduces pressure surges and other destructive phenomena.The intake of air in response to negative pressure protects the system from destructive vacuum conditions and prevents damage caused by water column separation. Air entry is essential to efficiently drain the system.The automatic air release component releases entrapped air in pressurized systems.

Without air valves, pockets of accumulated air may cause the following hydraulic disturbances: - Restriction of effective flow due to a throttling effect as would a partially closed valve. In extreme cases this will cause complete flow stoppage.- Obstruction of efficient hydraulic transmission due to air flow disturbances.- Accelerate cavitation damages.- Pressure transients and surges. - Corrosion in pipes, fittings and accessories.

- Danger of high-energy bursts of compressed air.- Inaccuracies in flow metering.

As the system starts to fill, the combination wastewater valve functions according to the following stages: 1. Entrapped air/gas is discharged by the valve.2. When the liquid level reaches the valve’s lower portion, the lower float is lifted, pushing the sealing mechanism to its sealing position. 3. The entrapped air is confined in a pocket between the liquid and the sealing mechanism. The air pressure is equal to the system pressure. 4. Increases in system pressure compress the trapped air in the upper section of the conical chamber. The conical shape assures the height of the air gap. This enables separation of the liquid from the sealing mechanism. 5. Entrapped air (gas), accumulating at peaks and along the system, rises to the top of the valve, and displaces the liquid in the valve’s body. 6. When the liquid level is lowered to a point where the float is no longer buoyant, the float drops, unsealing the rolling seal. The air release orifice opens and allows part of the air that accumulated in the upper portion of the valve to be released to the atmosphere. 7. Liquid enters the valve. The float rises, pushing the rolling seal to its sealing position. The remaining air gap prevents the wastewater from fouling the mechanism.

When internal pressure falls below atmospheric pressure (negative pressure): 1. The floats will immediately drop down, opening the air & vacuum and air release orifices.2. Air enters into the system.

Main Features- Working pressure range: 0.2 - 10 bar Testing pressure: 16 bar - Maximum working temperature: 60° C. - Maximum intermittent temperature: 90° C.- The unique design of the valve prevents contact between the wastewater and the sealing mechanism by creating an air gap at the top of the valve. These features are achieved by: • The conical body shape: designed to maintain the maximum distance between the liquid and the sealing mechanism and still obtain minimum body length. • Spring-loaded joint between the stem and the upper float: vibrations of the lower float will not unseal the air release component. Release of air will occur only after enough air accumulates.

Automatic Air Release Valve

Description The S-050 series Automatic Air Release Valve releases accumulated air from the system while it is under pressure. The presence of air in a water system can reduce the effective cross sectional flow area resulting in increased head loss and decreased flow. Unwanted air may also cause water hammer and metering inaccuracies, while hastening corrosion.In spite of its compact and light weight structure, the S-050 series Automatic Air Release Valve has a 12mm² orifice that enables it to release air at high flow rates and is not exposed to obstruction by debris.

Applications - On most types of pumps. - After filters, pressure reducers and fertilizer injection systems.

Operation The automatic air release valve releases entrapped air from pressurized systems.


The valve functions while the system is under pressure, according to the following stages:1. Entrapped air, which accumulates at peaks and along the system, rises to the top of the valve, which in turn displaces the liquid in the valve’s body.2. The float descends, unsealing the rolling seal. The automatic air release orifice opens and the accumulated air is released.3. Liquid enters the valve and the float rises, pushing the rolling seal back to its sealing position.Note: Automatic air release valves are designed to release air as itaccumulates at peaks in pressurized systems. They are not normallyrecommended for vacuum protection or for discharging large volumes of air, because of their inherently small orifices. For this

purpose, air & vacuum valves are recommended as they have much larger orifices.However, automatic air release valves will permit air to enter the system under vacuum conditions. If this is not desirable, specify the one-way out check valve.

Main Features - Working pressure range: SG-10 0.1 - 10 bar S-050 0.2 - 16 bar- Test pressure for the air valve is 1.5 times its working pressure. - Maximum working temperature: 60° C. - Maximum intermittent temperature: 90° C.- The body is made of high strength composite materials and all operating parts are made of specially selected corrosion- resistant materials.- The larger than usual orifice enables it to release air at higher flow rates than other automatic air release valves of its kind.- The large orifice with its self-cleaning mechanism dramatically reducesobstruction due to debris.- The valve’s rolling seal mechanism design is less sensitive to different pressures than a direct float seal, thus enabling a one sizeorifice for a wide pressure range (from 0.2 up to 10/16 bar).- Light weight, simple and reliable structure.- A drainage outlet enables removal of excess fluids.

Valve Selection - Available in male threaded sizes: 1/2”, 3/4”, 1” - BSP / NPT - One-way out check valve - available as a valve that will only releaseair from the system and will not admit air to the system when negativepressure conditions occur. This characteristic is obtained by adding acheck valve to the air outlet.

Entrapped air (gas), accumulating at peaks and along the system, rises to the top of the valve, and displaces the liquid in the valve’s body. 5. When the liquid level is lowered to a point where the float is no longer buoyant, the float drops, unsealing the rolling seal. The air release orifice opens and allows part of the air that accumulated in the upper portion of the valve to be released to the atmosphere. 6. Liquid enters the valve. The float rises, pushing the rolling seal to its sealing position. The remaining air gap prevents the wastewater from fouling the mechanism.

Note: the automatic air valves are specifically designed to release air as it accumulates at the high points of a pressurized, operating system. Because of their inherently small orifice size, they are not recommended for vacuum protection or for discharging large quantities of air or gas, although they will admit some air into the system under vacuum conditions.

Main Features- Working pressure range: 0.2 - 10 bar - Testing pressure: 16 bar - Maximum working temperature: 60° C. - Maximum intermittent temperature: 90° C.- Body made of composite plastic material, resistant to corrosion.- Internal metal parts are made of corrosion-resistant stainless steel.- Floats are made of composite materials.- Flexible rolling seal provides smooth positive opening, closing, and leak-free sealing over a wide range of pressure differentials.- 1/8” threaded discharge outlet enables removal of excess fluids.- Drainage tap with ball valve is provided.- The unique design of the valve prevents contact between the wastewater and the sealing mechanism by creating an air gap at the top of the valve. These features are achieved by: • The conical body shape: designed to maintain the maximum distance between the liquid and the sealing mechanism and still obtain minimum body length. • Funnel-shaped lower body: designed to ensure that residue wastewater matter will fall back into the system and be carried away by the main pipe. • Rolling Seal: provides smooth positive opening, closing, and leak- free sealing over a wide range of pressure differentials. - 1/4” ball valve releases trapped pressure and drains the valve body prior to maintenance.

Valve Selection- Size Range: 1”& 2”, BSP or NPT male threaded connection or flanged to meet any requested standard.- Flanges are manufactured of composite materials.- Additional one-way out check valve attachment allows air discharge, not allowing air intake.- For best suitability, it is recommended to send the fluid chemical properties along with the valve request.
