Cla-Val Series 34 Air Release Valves are designed to vent entrainedair that collects at high points in a pipeline. This valve continuouslyeliminates air from a system by releasing small quantities of air beforelarge air pockets can occur. In many installations, continuing accumu-lations of air in the pipeline (lacking air release valves); cause flowcapacity to slowly decrease; power consumption slowly increases; un-noticeable at first, until flow drops dramatically, even stopping due toair blocks in the piping. Another problem resulting from excessive airaccumulation is un-explained pipeline rupture. These ruptures arepassed off as the result of ground settling or defective pipe, Where asin reality its large air pockets that greatly increase pressure surges(normally occurring) when flow stops and starts causing the rupture.During normal pipeline operation, air accumulation at the high point willdisplace the liquid within the air valve and lower the water level in rela-tion to the float. As level of the liquid lowers, where the float is no longerbuoyant, the float drops and opens the valve orifice seat and permittingaccumulated air to be exhausted to atmosphere. After air is released,the liquid level in the air valve rises and closes the valve orifice seat.This cycle automatically repeats as air accumulates inside the airrelease valve, thereby preventing the formation of air pockets
Series 34
Air Release Valves
InstallationSeries 34 Air Release Valves are typically installed at high-points in pipelines and at regular intervals, of approximate1/2 mile, along uniform grade line pipe.
Mount the unit in the vertical position on top of the pipelinewith an isolation valve installed below each valve in theevent servicing is required. A vault with adequate air ventingand drainage is recommended.
Note:Vacuum check valves can be supplied on the discharge ofall size air release valves to prevent air re-entering the system;during negative pressure conditions
Purchase SpecificationsThe air release valve shall be of the float operated, simplelever or compound lever design, and capable ofautomatically releasing accumulated air from a fluid systemwhile the system is pressurized and operating.
An adjustable designed orifice button shall be used to sealthe valve discharge port with drip-tight shut-off. The orificediameter must be sized for use within a given operatingpressure range to insure maximum air venting capacity.

Air Release Valve Sizing for Water and Wastewater Pipelines1. Air release valve sizing requires determining the volume of air that must be released from pipeline high points during normal operation and the
diameter of the pipeline. Series 34 Air Release Valves are primarily used to continuously release pockets of air (as they develop) from high points. Hence it is not critical to determine exact volume of air to be released.
2. If the volume of air to be released has been determined, then use the venting capacity chart on page 5 to assist in sizing the air release valve. Use maximum pipeline operating pressure (in psi) and flow (in SCFM) to determine orifice size. Select the largest inlet size for each valve to insure adequate venting capacity.
FOR WATER AND
INSTALLATION TIPS1. The effectiveness of Series 34 Air Release Valve is dependent upon it being located at appropriate high points in a pipeline and
at uniform intervals of approximately 2500 feet on horizontal pipelines.2. There are four variables that can cause an air pocket to form slightly downstream of the true high point in a piping system:
1. Severity of the slope adjacent to the high point or change of gradient2. Velocity of the liquid3. Texture of the inside surface of the pipe being used4. Viscosity of the fluid
It is recommended where an air pocket can form slightly downstream of the high point, to install additional Series 34 Air ReleaseValve at this point.
3. Cla-Val has available, upon request, a Slide Rule Air Valve Calculator. It will greatly reduce the amount of time to size valves for pipeline service.

Air and Vacuum Valve Sizing - Combination Air Vacuum Valves - Vacuum Breaker Valves1. Series 35 Air and Vacuum Valves should be sized to handle the maximum amount of air to be exhausted or admitted into the
pipeline and not exceed an acceptable pressure differential across the valve.2. Each high point or change in grade must be examined independently when determining valve size. Use the steepest slope
for calculations.3. Use the flow capacity charts (A) and (B) on page 15 to assist sizing Air and Vacuum Valves.4. Determine the smallest valve size capable of exhausting air equal to the filling rate of the pipeline in CFS while
not exceeding a pressure differential of 2 psi across the valve orifice. (Based on pump capacity).
The following formula is recommended to calculate the rate of flow in CFS for filling the pipeline:
Where: CFS = Cubic feet per secondGPM= Gallons per minute
5. Determine the smallest valve size capable of admitting air equal to the potential flow in CFS while not exceeding a pressure differential of 5 psi across the valve orifice. (Based on gravity flow).
The following formula should be used to calculate the rate of flow in CFS that can occur within the pipeline under gravity flowconditions. (During Initial Filling • During Intentional Draining • During A Pipeline Rupture)
Where: Q = Flow of water in cubic feet per secondC = Coefficient in Chezy’s formula = 110S = Slope in feet per foot of lengthD = Inside pipe diameter in inches
6. If thin wall pipe is being used, the risk of pipeline collapse due to the formation of vacuum must be considered. The following formula may be used to calculate the collapsing pressure of thin walled cylindrical steel pipe using a safety factor of four:
Where: P = Collapsing pressure in psiT = Thickness of pipe in inchesD = Diameter of pipe in inches
7. For other pipe materials or thickness consult pipe manufacturer for pipe collapsing pressure.
8. Determine the smallest valve size capable of admitting the required air in CFS (as found in step 5) without exceeding the collapsing pressure (as found in step 6) or 5 psi, whichever is less. Do not exceed a pressure differential greater than 5 psi.
9. Finally compare the valve size determined in step 4 with the valve size determined in steps 5 or 6. If they differ, always select the larger valve size.
Note: Cla-Val has available upon request, a Slide Rule Air Vacuum Valve Calculator that greatly reduces the amount of time necessary to size valves for pipeline service. Includes-GPM, MGD, CFS, Liter/Sec. & Pipeline Velocity Conversions.

• Provides High Capacity Air Venting and Air Intake• Stainless Steel T316 Trim Standard• Stainless Steel Floats Guaranteed• Fully Ported Valves - No Restrictions• Designed For Drip Tight Seal At Low Pressures
The Cla-Val Series 35 Air and Vacuum Valve is designed to performtwo separate functions. First, it will allow large quantities of air to beexhausted from the pipeline as it is being filled with water. Whenthis air has been vented completely, water will enter the valvecausing the float to seal tightly against the seat to prevent waterflow. Secondly, if the line is being drained, either intentionally or asa result of pipeline breakage, the valve responds to the loss inpressure and opens. This allows air to re-enter the pipeline andprevents potentially damaging vacuum from developing.
Note: The Series 35 does not open under pressure to exhaustsmall quantities of air which may collect at high points duringsystem normal operation. Series 34 Air Release Valve is requiredfor this function.
Note: See Sizing Guide Pages 14 & 15

The air and vacuum valveportion shall automatically exhaust large quantities of airduring the filling of the pipeline and automatically allow airto reenter the pipeline when the internal pressure of thepipeline approaches a negative value due to column sepa-ration, draining of the pipeline, or other emergency. The airrelease valve portion shall automatically release smallamounts of air from the pipeline while it is under pressure.
The inlet and outlet of the valve shall have the same cross-section area. The float shall be guided by a stainless steelguide shaft and seat drip tight against a synthetic rubberseal. 4" and larger valves shall have dual guided shafts ofhexagonal cross section and a protective discharge hood.
The float shall be of all stainless steel construction and capableof withstanding maximum system surge pressure withoutfailure. The body and cover shall be concentrically locatedand of cast iron and the valve internal parts shall be of T316stainless steel or Buna-N® rubber.
The Combination Air Release and Vacuum Valve shall bemanufactured per ANSI/AWWA C512-04 Series 36 from Cla-Val., Newport Beach, CA, U.S.A.
Combination Air Release andVacuum Valve
• Stainless Steel T316 Standard• Stainless Steel T316 Floats Guaranteed• Fully Ported Valves - No Restrictions• Easily Serviced Without Removal From Pipeline• Engineered For Drip Tight Seal At Low Pressures
The Cla-Val Series 36 Air and Vacuum Valve is a multipurposevalve that combines the operation of both the Model 34 AirRelease Valve and Model 35 Air and Vacuum Valve. It functionsto exhaust large quantities of air in the pipeline during the fillingcycle and to admit air, as necessary, to prevent potentiallydangerous vacuum from forming when being emptied eitherintentionally or as a result of pipeline breakage.
InstallationThe Series 36 Combination Air Valve should be installed athigh points at grade changes within the pipeline.
Mount the unit in the vertical position on top of the pipelinewith an isolation valve installed below each valve in theevent servicing is required. A vault with adequate ventingand drainage should also be provided.

• 100% Vacuum Protection - No Restrictions
• Engineered For Drip Tight Seal At Low PressuresSeries 37 Well Service Air Valves regulate air discharge from thepump column to prevent shock and air entering the system witheach start. Conversely with each pump stop, full flow unrestrictedair, is allowed back into the column preventing vacuum forming,which can damage pump steals, but also to prevent the pumprestarting against a full head in the column because vacuum willprevent the pump column to drain. Under this condition severedamage to the pump, controls and piping can occur.
All the preceding is accomplished by means of a unique air throt-tling device (double port) and an arrestor check with built in anti-shock feature.
Well service air vacuum valves, once closed and pressured do notopen to air release under pressure.
See series 34 Air Release Valves page 5.
InstallationThe Series 37 Well Service Valve is typically installed betweenthe pump discharge and check valve. Mount the unit in thevertical position on top of the pipeline with an isolation valveinstalled below the valve in the event servicing is required.Provide adequate air venting inside the pump station and fromair valve vaults on pipelines.
Design / Purchase SpecificationsThe Well service air valves shall automatically exhaust largequantities of air in the pump column during pump start-upand allow air to re-enter the column during pump shut-down.The air valve shall be designed for installation between out-let of vertical turbine pumps and the inlet of the pump checkvalve.

Series 37 Well Service Valves (Light Duty)well service valves are supplied without airthrottle device. Instead it is fitted with awater diffuser that function like a waterfaucet bubbler to break down a solid col-umn of water into small streams there byallowing the water to raise the air valvefloat slowly into the closed position.Recommended where operating pumppressure are below 40 PSI and GPMvelocities less than 5’ per/sec
Flanged Series 37 Well & Pipeline serviceair valves are supplied with Arrestor CheckValves, function to stop the flow of water,(for a fraction of a second) entering theupper chamber of the air valve. TheArrestor Check then opens instantly, waterenters the air valve, all air is exhaustedand the air valve shuts. This ArrestorCheck action allows for a slow non shockair valve shut-off. To prevent pump orpipeline damage the shut-off/open actionof the arrestor check occurs practicallyinstantaneously. It is self regulating andrequires no adjustment in the field.Arrestor Check air valves are recommend-ed at high points where velocitiesapproach 10’ / second in the main line.

Air Release & Vacuum Breaker Valve(Threaded & Flanged)
Sizes 1" - 2" - 3" - 4" - 6"Series 33A
OperationAir Release Mode—Valve is normally open.When line is filled or pump started, air is exhausted through the normally open33A valve. As liquid fills the valve, float ball rises to form a drip-tight closureand remaining air is exhausted through small orifice.
Vacuum Prevent Mode When line pressure drops below positive pressureand the liquid level lowers, the float drops, unseating the valve and allowingair into the line, thus preventing a vacuum.
Note: Available for Sea Water Service See Material Specifications
Installation
Series 33A Air Release and Vacuum Breaker Valves are typicallyinstalled at high points in pipelines for air release, or at anticipated pipelinevacuum occurrence locations. Install Series 33A at regular intervals(approximately 1/2 mile) along uniform grade line pipe. Mount the unit in thevertical position on top of the pipeline, and include an isolation/shutoff valve.
Series 33A is often installed upstream of check valves in pump dischargesto vent air during start-up and to allow air reentry when the pump stops.
• Standard Max. D.W.P. 300 psi (For Higher Operating Pressures Consult Factory)
• Transmission Pipeline High Points
• Water Treatment Plant Piping High Points
• Offshore Platforms
• Vertical Turbine Pump Discharge
Typical Applications
• Automatically Eliminates Air Pockets• Easily Serviced Without Removal from Pipeline• Simple, Effective Patented Design• Corrosion Resistant Materials of Construction• Engineered For Lasting Service
Designed to protect pipelines and vertical turbine pump appli-cations on offshore platforms from air lock and vacuum col-lapse, the Cla-Val Model 33A Air Release and VacuumBreaker Valve eliminates air and prevents vacuum formationsin pipelines. A large venting orifice and large float clearancesfreely exhaust or admits air during pipeline filling or draining.
During normal pipeline operation, air accumulation and buoy-ancy cause the float ball to lower or lift. As the water levellowers inside the valve, small amounts of accumulated air arereleased through the small orifice. Once air is released, thepatented float poppet system closes drip tight.
Valve servicing is simple because the entire float poppet sys-tem, can be replaced without removal of the valve body fromthe pipeline.

Vacuum Breaker / Air ReleaseValves for Water and Wastewater
VACUUM PREVENTION AND SLOW AIR RELEASE FORPRESSURE SURGE CONTROL
Cla-Val Vacuum Breakers are reliable and economical pipeline surgecontrol components, requiring no regular maintenance.
Standard valves are designed to open with minimal (1/4 psi) pressuredifferential across the orifice. Higher or lower relief settings are available.
The Vacuum Breaker Valve (Large orifice combined with Air ReleaseValve (small orifice) are normally closed. But when installed at pointswhere water column separation can occur, both orifices open admittingair into pipeline, then instantly close to trap air and thereby cushioningrejoining of the water column. In this manner severe pressure surge/waterhammer is prevented as the system returns to normal operation.
Simultaneously the small orifice Air Release Valve opened due to vacu-um and stays open venting the discharge of trapped air from pipelineslowly until gradual normal pipeline pressure is achieved. Various smallorifice are available. See small orifice chart.
Water column separation in a pipeline may create high levels of vacuumonly momentarily, but severe damage, such as a pipeline rupture canoccur when the water column rejoins. Also momentarily vacuum condi-tions can easily cause a thin wall pipeline or sealed water tank to col-lapse due to vacuum when draining fluid. Metal to Buna-N® insures “droptight” seal at any pressure. For these reasons it is sound engineeringpractice to use Cla-Val Vacuum Breaker Air Release Valves to preventwater column separation in pipelines and collapse of tanks.

Vacuum Breaker Valve (Air Intake)
Series 31PARTS LIST
Operating Description
This valve is pressure type vacuum relief valve designedto open when line pressure is below atmospheric. Thelarge inlet ports are designed to admit air to the line withminimum of restriction.The design is very simple with only one moving part.Controlling vacuum is transmitted directly to thediaphragm chamber through the hollow stem. A largediaphragm area helps insure sensitive operation.At pressure above atmospheric the valve is tightlyclosed. The composition disc insures tight sealing evenat low pressure. The diaphragm is heavily reinforced withnylon fabric.

Series 34-WWWASTEWATER SERVICE
AIR RELEASE VALVES• Stainless Steel T316 Trim Standard• Stainless Steel Floats Guaranteed• Easily Serviced Without Removal From Pipeline• Engineered For Drip Tight Seal At Low Pressures• Optional Backwash Kit Available
The Cla-Val series 34WW Air Release Valve is speciallydesigned for sewage service. It will protect pipelines fromentrained air or gases that collect at high points in sewagepipelines. This valve effectively eliminates air from a system byreleasing small amounts of air before large air pockets canoccur. In extreme cases, the continued accumulation of air with-out release valves can actually stop flow completely. Increasedpower consumption and associated power costs can beanticipated if systems are not properly designed to releaseaccumulated air.
During normal operation, air and gas accumulation will displacethe liquid within the valve and lower the liquid level in relation tothe float. When the level of the liquid lowers to where the float isno longer buoyant, the float will lower and using a mechanicallever will open the valve seat to permit the accumulated air to beexhausted to atmosphere. As air is released, liquid level in thevalve raises the float and closes the valve seat. This cycle isautomatically repeated as often as necessary.
Installation
Series 34WW Air Release Valves are typically installed at highpoints in pipelines and at regular intervals of approximately 1/2mile, along horizontal pipelines.
Mount the unit in the vertical position on top of the pipeline withan isolation valve installed below each valve in the eventservicing is required. A vault with adequate venting and drainageshould also be provided.
For regular cleaning to keep sewage equipment in good workingcondition use the optional customer installed BWKT BackwashKit with back flushing hose and quick disconnect couplings.
Purchase SpecificationsThe air release valve shall be of the float operated, com-pound lever design, and capable of automatically releasingaccumulated air, gas or vapor from a pressurized fluid systemwhile it is in operation.
An adjustable featured orifice shall be used to seal the valvedischarge port with drip-tight shut-off. The orifice diametermust be sized for use within a given operating pressure rangeto insure maximum discharge capacity.

The Cla-Val Series 35WW Air and Vacuum Valve is designed toperform two separate functions in a sewage or wastewater system.First, it will allow large quantities of air to be exhausted from thepipeline as it is being filled. When this air has been ventedcompletely, liquid will enter the valve causing the float to seal tightlyagainst the seat. Secondly, if the line is being drained, the valveresponds to the loss in pressure and opens. This allows air tore-enter the pipeline and prevents potentially damaging vacuumfrom developing.
The Series 35WW does not open under pressure to exhaust smallquantities of air which may collect at high points during systemnormal operation. Model 34WW Air Release Valve is required forthis function. For both functions, select Model 36WW CombinationAir Release and Vacuum Valve.

The Cla-Val Series 36WW Combination Air and Vacuum Valveis a multipurpose valve that combines the operation of both theSeries 34WW Air Release Valve and Series 35WW Air andVacuum Valve, especially for sewage and wastewater applications.It functions to exhaust large quantities of air in the pipeline duringthe filling cycle and to admit air, as necessary, to prevent apotentially dangerous vacuum from forming when being emptiedeither intentionally or as a result of pipeline breakage.
Note: For Valve sizing see Formula page 14.
InstallationThe Series 36WW Combination Air Valve should be installedat high points and grade changes within the pipeline.
Mount the unit in the vertical position on top of the pipeline withan isolation valve installed below each valve in the event servicingis required. A vault with adequate venting and drainage shouldalso be provided.
For regular cleaning to keep sewage equipment in good workingcondition use the optional customer installed BWKT BackwashKit with back flushing hose and quick disconnect couplings.
Purchase SpecificationThe combination air valve shall combine the operatingfeatures of both an air and vacuum valve and an air releasevalve in one housing. The air and vacuum valve portion shallautomatically exhaust large quantities of air during the fillingof the pipeline and automatically allow air to reenter thepipeline when the internal pressure of the pipeline approachesa negative value due to column separation, draining of thepipeline, or other emergency. The air release valve portionshall automatically release small amounts of air from thepipeline while it is under pressure.
The inlet and outlet of the valve shall have the same cross-section area. The float shall be guided by a stainless steelguide shaft and seat drip-tight against a synthetic rubberseal.
The float shall be of all stainless steel construction andcapable of withstanding maximum system surge pressurewithout failure. The body and cover shall be concentricallylocated and of cast iron and all valve internal parts shall beT316 stainless steel with Buna-N® rubber seat. Must beManufactured per ANSI/AWWA C512-04
The Combination Air Release and Vacuum Valve shall beModel 36WW from Cla-Val., Newport Beach, CA, U.S.A.

All Cla-Val Series 582 Two-Door Check Valves utilize a torsionsprings that very quickly shut the valve, before flow reversal. To min-imize Slam / Water Hammer typically experienced with con-ventional swing check valves. Basically Two Door designvalves, halves the travel distance from open valve to shut-offvs swing check valves and is the reason for the Anti-slam /Minimum Water Hammer feature. With extremely short layinglengths series 582W and Series 582 are space savings & aneconomical solution. The Series 582G with grooved ends pro-vides for ease of installation and removal from pipelines.Although lighter in weight than conventional swing checkvalves, Cla-Val Two-Door Wafer Check Valves are designed forheavy-duty applications. For ease of installation, valves 6” andlarger are supplied with lifting eye bolts. All materials conform toASTM specifications, ensuring long lasting reliable performance.

Valve Body: Cast Iron ASTM A126, Class BSeat and Plug: Bronze ASTM B584 Alloy C83600 Strainer Heavy Gauge 1/16”: Thick Stainless Steel T316Exterior coated with Universal ALKYDTest Certificate, Drawings, Parts List and O&M ManualProvided upon RequestSeries 38 -“Tite Seal” Foot Valves as provided by Cla-Val, Newport Beach, CA U.S.A. 92759-0325
Cla-Val “Tite Seal” foot valves provide years of trouble free opera-tion at low or high pressures. The special Buna-N® seal allowsinitial contact to the metal plug, for zero leakage, then as pres-sure builds, the Buna-N® seal is compressed only slightly until theplug fully contacts the metal seat preventing further compressionof the Buna-N® seal. In this manner the seal cannot be damagedfrom compression and pump prime is always assured. A 360degree stainless steel strainer (not plated steel) is providedstandard with at least, three times flow-thru area of the foot valvesize. This greatly enlarged flow thru area strainer means full flowcan be maintained even should some small particles collectagainst the strainer. Cla-Val “Tite Seal” Foot Valves provide non-shock and silent shut-off.

Series 584
Flex-Check Valve™
The Cla-Val Model 584 Flex-Check Valve is designed for longservice life and maintenance free check valve operation comparedto traditional swing check valves. It has a full-flow area body withintegral seat at 45° angle to reduce head loss. This minimizes disctravel to 35° degrees for improved no-slam check action and forreliable vertical up flow operation even on slurry applications.Body and Cover are fusion bonded NSF-61 epoxy coated for longservice life on potable and non-potable systems. Unique one-piece steel and nylon reinforced Buna-N rubber disc assemblyflexes to eliminate traditional metal hinge problems. During sys-tem flowing conditions the disc flexes up to the open positionallowing unrestricted flow through the valve. When systemreverse flow conditions occur the disc flexes down to the closedposition for drop-tight seal preventing reverse flow. The flex-discreliability is test-proven to over one million cycles. The optionalReturn Flow Actuator offers manual opening for pump priming,back flushing, draining lines, or system testing needs and is easyto field install.
• Full Pipe Size Flow Area
• Drop Tight Seating
• Non-Slam Closure
• Fusion Bonded Epoxy NSF-61
• Optional Return Flow Actuator
