Characteristic Curves

The Inherent flow characteristic of a control valve is the relationship between the flow and the lift of the plug at a constant pressure drop.

The characteristics normally available, are shown.

Linear - Flow is directly proportional to valve lift.

Equal % - Flow change by a constant percentage of its instantaneous value for each unit of valve lift.

Quick opening - Flow increases rapidly with initial travel reaching near its maximum at a low lift.

Cage Trim Design



ED Multi Stage Trim

• Several mechanisms are utilised in the ED trim design to assist with the conversion of potential energy (pressure) into heat without problems of cavitation in liquids and the problems of high noise levels, with gases caused by high velocities.

l Splitting the flow within the ED trim into a large number of small streams reduces the energy levels in each stream.

l Large trim surface area maximises friction against the fluid within the trim design.

l Large number of changes of direction assist the pressure reduction.

l Repeated compression and expansion optimises the design.

l The pressure drop is taken in a geometric progression across each of the restrictions, resulting in the smallest number of stages for the process conditions.

l The disk stack consists of a multiple set of tortuous paths in parallel to each other, with each pathway being a series of restrictions in series with each other.

l In a modulating service, the flow experiences the same pressure drop conditions at low flow rates as it does with high flows.

l In liquid applications the expansion chambers cause swirling of the fluid increasing the pressure reduction achieved.

l The disks are clamped in position by means of the bonnet bolting. This ensures the stack can be easily extracted and separated for cleaning.

l Disks are of substantial thickness and so do not suffer from distortion.

l The clamping forces are applied through solid material with a large area of contact, eliminating the chance of collapse of the discs.

l Trim options include Linear Flow Characteristic, Bi-linear and Tri-linear.

l Other multi Stage trim designs are available on request.

Series 170 Angle Control and Choke Valves The Series 170 Control Valve product range emulates the Series 110 design except that the valve body is an angle type constitution instead of a globe style.This range of control valves can be fitted with the same trim design options as the Series 110 product. It is used where the pipework configuration necessitates an angle pattern design.The Series 170 can also be adapted to

the choke valve application and again fitted with a selection of trim designs to suit each application in conjunction with the angle body configuration.This range can be fitted with standard and severe service trim designs.In conjunction with this the trims could be supplied manufactured in hard metal for potentially erosiveapplications.

Regulator Types

All types of regulators generally fit in to one of the following two basic categories.1 Direct Operated2 Pilot Operated

The specific considerations particular to your control needs are to be carefully studied andunderstood to determine which method of control is the

better choice. Regulators when compared to control Valve / Instrument package have their advantages and limitations. The table below lists selected

characteristics of both.The operational principal of both types of regulators is explained as follows.

B Pilot OperatedA pilot operated system uses a two-path control. In two path control, the main valvediaphragm responds quickly to downstream pressure changes, causing an immediate correction in the main valve position. At the same time, the pilot diaphragm diverts some ofthe reduced inlet pressure to the other side of the valve diaphragm, control the final positioning

A Direct OperatedIn operation, a directoperated, pressure reducing regulator senses the downstream pressure through either internal pressure registration or an external control line. This downstream pressure opposes a spring which moves the diaphragm and valve plug to change the size of the flow path

through the regulator.Characteristically direct operator regulators are adequate for narrow-range control, and where the allowable change in output pressure can be 10 to 20% of the outlet pressure setting. This 10 to 20% is typical although finer control can be achieved depending on the specific application requirement.

of the main valve plug. Two-path control result in fast response.Pilot-operated regulators are preferred for broad-range control, or where the allowable change in outlet pressure is required to be less than 10 percent of the outlet pressure setting. They are also commonly used when remote set point adjustment is required for a regulatorapplication.

Series 700

Upstream Pressure Regulating Valves - Series 700These are self operated upstream pressure regulating control valves, used in many applications for limiting pressure buildup (i.e. prevent overpressure) at its location in the pressure system. The valve opens in proportion to the inlet pressure preventing a rise of

internal pressure in excess of a specified value. These valves are used on a wide range of applications in the chemical process industry for up-stream pressure control,eg: Refineries, Fertiliser and Petrochemical Plants, Pharmaceutical and Food Processing Plants.

Series 400

Diaphragm Control ValvesSeries 400The Diaphragm Valve is essentially a simple pinch clamp, closed by pressing a flexible diaphragm against transverse weir, when fully closed, the diaphragm seats against the weir providing a leak tight closure.

The diaphragm valves are recommended for handling sticky and viscous fluids, slurries and highly corrosive and hazardous substances and other hard to handle mediums or where tight closure is

prime factor. It is the most ideal valve to handle fluids that require high purity and should remain free from contamination.

The Diaphragm Valve is a simple pinch type valve and of low pressure type because of large area of diaphragm and is extensively used for both On/Off and throttling services and finds its application in Waste and Water Treatment Plants, Filtration Plants, Chlorination Plants etc.

l The valve should be installed preferably in a straight run of the pipe, a few diameters away from the bends. The preferred position is with actuator vertically above or below the valve body. It may also be installed in a horizontal or angled position provided the diaphragm actuator is supported.

l Necessary clearance should be provided above the actuator to permit removal for servicing or for inspection of the valve internals. The supply pressure to the actuator be either 20 psig or 35 psig or as per rating indicated on the name plate.

l For control applications, positioner mounted are piped and adjusted at the factory.

Final checkl After the valve has been installed, check the operations for full stroke travel as indicated on the name plate.

l Check for air leaks in air line connection. Open and close the valve two or three times to ensure proper operation.

l Before commissioning the process flow, it would be advisable to use conical filter or other temporary devices to avoid damage to the rubber lining or body diaphragm as the fluid is likely to carry foreign solid material during testing or commissioning of the plant.

l This care is particularly important with neoprene or other soft elastomer lining. Special care has to be exercised with glass lining construction.

l It is generally not desirable to use excessive air pressure to the actuator than specified as it would reduce the life of the body diaphragm and also cause undue forces on the actuator diaphragm.

l Valves having manual hand wheels should be preferably operated with air pressure, particularly during the start of the plant when any foreign material is likely to damage the internals.

l For the most efficient use of heat energy from steam, it is necessary to reduce the temperature of superheated steam to near the saturation temperature.

l The high temperature of superheated steam provides the large amount of energy that is used for water vaporisation resulting in an increased flow of steam at a lower temperature.

l By having the amount of water added the temperature is controlled.

l The rate of cooling depending on spray water drop size, distribution and velocity.

Figure 2 Minimum Steam velocity for Pipe Desuperheating Units

Satisfactory desuperheating is dependant on the correct selection and installation of a unit for a particular application. The following guidelines detail the installation requirements to achieve maximum efficiency from a desuperheating unit.

1 The installation of aDesuperheater unit should be with the flange orientation aswith the drawing opposite.

2 Units may be located in suitable horizontal or vertical down pipe work.

3 Minimum length of straight pipe work following Desuperheating unit should be6 to 8 pipe diameters.

4 Steam pipe work to fall in direction of flow by minimum 20mm in 1000mm.

5 Condensate supply to be free

of debris and effectively filtered to less than 0.25mm.

6 Efficient drainage of Desuperheater pipe work is essential. Large condensatetraps for 10% maximum flow are required to facilitate start-up and shut down of plant.

7 Lagged pipe work assist successful Desuperheating.

8 Controlled temperature to be higher than 6°C (11°F ) above saturation point.

9 To achieve satisfactory evaporation the percentage ratio of water to steam should not exceed 15%. The exact value is dependant on each application and the factory should be consulted if this figure is to be exceeded.

10 Where the Variatrol unit is required to shut off for long

periods it is recommended that an upstream motorized isolating valve is incorporated intothe system.

11 The temperature pocket should extend into the pipe 1/3 to 1/2 pipe diameter for steam pipes up to ǿ 300mm and 1/4 to 1/3 on steam pipe diametersabove ǿ300mm.

12 The minimum distance of the temperature sensor point from the desuperheating unit shown in figure 1.

13 For maximum steam turndown applications, a high superior pressure ofcondensate is necessary.

14 Maximum recommended liner velocity 330 ft/s (100 m/s). The minimum liner velocity is taken from the graph shown in figure 2.

1) The valve should preferably be installed with actuator verti-cally above or below the valve body. It can be installed in a horizontal or angled position if actuator is suitably supported.

2) Necessary clearance should be provided above the actuator to permit servicing.

3) The flange bolts are to be tightened evenly to avoid

placing strain on the body.

4) The inlet of air pressure regulator (Air set) should be connected to the pneumatic supply line.

5) Supply pressure to the diaphragm actuator should be either 1.5 kg/cm² (20psig) or 2.5 kg/cm² (35 psig) as per indication on the nameplate.

6) For cylinder actuator, supply pressure specified.

7) For control applications, the air set and valve positioner are mounted, piped and adjusted at the factory.

Final Check1) After installation, check the valve operation for full stroke as indicated on the nameplate, check for leaks in air line connection.

2) Open and close the valve

two or three times to ensure proper operation.

3) Before commissioning the process flow, it is essential to flush clean the piping properly. Ball valves require minimum maintenance for its operation.4) Apply a few drops of oil on the exposed guides and bushings, Hand wheel, if present, must be greased periodically.

l The VSL range of pneumatic piston actuators has been designed to provide powerful high performance for automatic control valves.

l Corrosion resistance to aggressive environments has led to careful consideration of component selection, whilst keeping in mind the need for weight reduction.

l Safety is an important consideration and spring containment has been carefully addressed so that inadvertent energy release has been eliminated.

l The foregoing conditions have led to unit being designed to accept air pressure up to 10 Bar, to provide thrust and stiffness.

l The end caps, piston, stems and tie bars are all either carbon or stainless steel, with the cylinder being a strong light composite material called Black Amalgon.

Piston Actuator Sizes Available

Actuator size (in²) 25 50 100 150 200 250

Standard stroke mm 50 80 80 80 100 100

This careful material selection makes the actuator inherently strong, durable and corrosion resistant.

l The spring is contained in a cage and the spring cap is secured with HT Steel tie rods and the nuts welded in place.

l This cage cartridge design prevents accidental unbolting of a pre-compressed spring and possibility of a catastrophic energy release.

l A further feature is the spring being contained inside the cylinder in a protected clean environment inhibiting atmospheric degradation.

l The actuator is also available as a spring-less double acting unit for even greater bidirectionan thrust.

l The following sizes are available as spring opposed pistons, double acting pistons or springless double acting pistons.

control instrument, positioners will reduce lag, thereby speeding up valve operation.

Split range

Some processes require the dual or sequential operation of two to three control valves by a single controller with a 3-15 psi output signal range.

Improves all performance

When process lags necessitate the use of wide controller proportional band, the positioner provides an exact means of making the control valve responsive to infinitely small changes in controller output pressure.

Non-standard controller output

The positioner is used to operate a valve with3-15 psi spring range when controller signal is other than 3 –15 psi.

Non-standard actuator spring range

The positioner is used to operate valves having non standard actuator spring ranges by controllers having the standard 3-15 psi signal pressure.

Accessories - Valve Positioner

l Pneumatic Valve Positioner is force balance device which, ensure the position of the plug, which is directly proportional to the controller output pressure.

l The Positioner compares the forces generated by the control signal and the control valve stem through the mo-tion connector and the feed back cam, and accordingly it feeds or bleeds the air going to the valve actuator.

l The instrument air signal is applied to the signal diaphragm. An increase in signal will drive the diaphragm and flapper-connecting stem to the right. The flapper-connecting stem will then open the supply flapper admitting supply pressure into the output which is connected to the actuator diaphragm. The exhaust flapper remains closed when the flapper connecting stem is deflected to right.

l The effect of increasing signal is to increase the pressure in the actuator. This increased pressure in the actuator drives the valve stem downward and rotates the positioner lever clockwise.

l This clockwise rotation of the lever results in a compression of range spring through cam. When the valve stem reaches the position called for by the controller, the compression in the range spring will give a balance

force resulting the closure of both the flapper.

l If the control signal is decreased, the force exerted by the signal diaphragm will also decrease and the force from the range spring will push the flapper-connecting stem to the left, opening the exhaust flapper.

l This causes a decrease actuator diaphragm pressure and allows the valve stem to move upward until a new force balance is established.

Accessories - Volume Booster

Volume Booster - Small CapacityVolume Booster is a high volume amplifier used to increase the operating speed of the actuator, preventing the time lags, in the systems where controller and the control valve are sep-arated by extremely long piping runs.Volume Booster receives the low

volume signal from the controller and transmits from an auxiliary supply a high volume signal to the control valve actuator.Volume Booster is specially recommended for the use with large capacity diaphragm actuator.

1 Input pressure acting upon the effective area of the upper diaphragm produces a force, which is opposed by the output pressure exerted upon the effective area of the lower diaphragm.

2 The opposing forces are in direct 1:1 ratio.

3 Hence any increase in the input pressure will cause the diaphragm assembly opening the pilot valve to admit a sufficient supply of air to the output to rebalance the input pressure.

4 A decrease in input pressure will cause the diaphragm assembly to lift off the exhaust port reducing the output and again rebalancing the input.

5 Equalising valve, by-passes slow small signal variations.

Accessories - Volume Booster

Volume Booster - Large CapacityHigh Volume Booster with a fixed minimum deadband is designed to substantially increase stroking speeds of large actuators. Actuators retain their normal slow and stable responses as long as their signal

fluctuations remain within the deadband limits that can be set on the booster.Volume Booster is specially recommended for the use with large capacity diaphragm actuator.

l During steady process conditions when Controller output variations are small, the controller or valve positioner signal to the booster input will be registered through the bypass valve directly to the actuator. l Both booster ports remain tightly shut; soft seats preventing unnecessary air consumption.

l Because of the bypass valve restriction, larger or faster signal changes will be registered sooner on the booster input than in the booster output chamber connected to the actuator.

l When the differential pressure exceeds the dead-band value of the booster, the diaphragm assembly will move so as to open one, or the other, booster port and allow rapidactuator pressure change. l When the controller or positioner senses that the corrective action is completed, the booster closes and lets the actuator return to normal operation.

Quick Response: Provides large volume for rapid stroking of the actuator when confronted with input signalsexceeding preset magnitude and rate capabilities.

l Stroking period can be reduced from one minute to less than three seconds using ¾” High Volume Booster on 300 sq. inch diaphragm actuator having 3 ½” stroke.

Greater Stability: Allows normally slow actuator response to the small or slow signal changes produced by usual process variations.

Low Air Consumption: Soft seats provide tight shutoff to prevent unnecessary air consumption.

Accuracy: Maintains correct actuator position at high stroking speeds.

Accessories - Air Lock

Air LockAir Lock is used when it is required to automatically hold the air pressure in diaphragm chamber of the actuator, on the same level in an event of failure of air supply. When supply pressure drops

below a preset value, the Air Lock Relay locks the air pressure in the diaphragm chamber of the actuator thereby holding the inner valve in one position, till the air supply is resumed.

Cut off Setting

1 The cut off setting is adjustable and is generally set at a much higher value than required for the operation of the control valve. 2 If the actuator pressure range is 0.2-1.0 Kg/cm², the setting of this relay could be much higher than 1.0 Kg/cm² as desired for cut off.

3 Where many control loops are involved, the setting of this relay therefore needs impulse

connection for cut off from the air supply header.

4 Cut off setting has been factory adjusted to the desired cut off value. Should it be required to re-adjust the cut off setting, this could be achieved either while the unit is already installed and connected to the system or separately on the test bench.

5 Inlet supply air and the outlet output gauge should

be available to re-adjust the setting.

6 To adjust the cut off setting,remove cap and adjust spring adjusting screw until desired outlet cut off pressure is achieved. Please note that air lock pressure differential is approx. 0.17 Kg/cm² higher than the set cut off pressure.

7 Turning the adjusting screw clock-wise will increase the cut off setting and turning anti-

clockwise will reduce the cut off setting. In this relay, a built-in manual relief valve is provided if the control valve has manual hand wheel. This exhausts the air from the diaphragm chamber when the hand wheel is operated to avoid damage to the actuator diaphragm.

8 Replace cap securely after having re-adjusting the cut off setting.
