eFirePump.com has relief valves for fire pumps and jockey pumps including UL Listed and FM approved valves for fire sprinkler systems. We provide brands such as Kunkle, Cla-Val, Cash Acme, and Val-Matic. 97% of our order ship within 1 business day!
Typical installation would be for use in conjunction with a turbine style jockey pump or where the jockey pump is capable of generating pressures which exceed the working pressure of the fire protection equipment or system.
This valve is recommended only for use as a jockey pump relief valve, not a fire pump casing relief valve.

The 3/4" Cla-Val Model 55L is a UL Listed and FM approved direct acting, spring loaded, diaphragm type pressure relief valve which can be installed in any position and is designed to open and close within very close pressure limits.
The adjustable pressure range is 20 to 200 PSI and typical installations are use as a fire pump casing/circulation relief valve or they may be installed downstream of a pressure reducing valve.
By removing and relocating the 3/4" plug in the valve body the new design permits installation in either an angle or straight orientation.
Typically ships in 1-2 days.

1/2", 3/4", and 1"
Air Release Valves, sometimes referred to as "small orifice valves," continually release unwanted air during system operation to protect against unwanted surges and maintain system efficiency.
Cla-Val model number 3410-AR 116.3
Comparable to Val-Matic model number 22.9
The Kunkle Figure 20 relief valve is an all bronze angle pattern liquid pressure relief valve with a pressure tight cap. The cap is removed to expose a drive screw and lock nut which is used to adjust the valve to the desired pressure setting.
(The Kunkle Figure 20 is neither UL Listed or FM approved and it is recommended that a Cla-Val 55L-60 be used for fire pump applications.)
3/4" MNPT x 3/4" FNPT
Designed for use in grid systems or any sprinkler system where pressure relief is required. The Adjustable Pressure Relief Valve can be adjusted from 75-200 psi. Adjustment to the desired pressure is achieved with the use of an approved fi re sprinkler system pressure gauge.
The adjustment cap is “diamond” knurled for easy adjustment. The body is cast bronze* and marked with directional arrows for proper fl ow indication. The pressure markings on the adjustment cap are for reference only. Use the system gauge for proper relief setting.
This valve is not for use as a fire pump or jockey pump casing relief valve.

The adjustable pressure range is 250-600 PSI and they are used as a fire pump casing/circulation relief valve for high pressure applications.
Note: This valve is not UL/FM listed or approved
Typically ships in 1-2 days.
100-300 PSI
The 1" Cla-Val Model 55L-60 is an UL Listed direct acting, spring loaded, diaphragm type pressure relief valve which can be installed in any position and is designed to open and close within very close pressure limits.
The adjustable pressure range is available as 100 to 300 PSI and typical installations are use as a fire pump casing/circulation relief valve or they may be installed downstream of a pressure reducing valve.
By removing and relocating the 1" plug in the valve body the new design permits installation in either an angle or straight orientation.
Typically ships in 1-2 days.
Cla-Val 2" Threaded Air and Vacuum Valve
Designed to protect pipelines from air lock and vacuum collapse, the CLA-VAL Model 33ATD Air Release and Vacuum Breaker Valve eliminates air and prevents vacuum formation in pipelines. A large venting orifice and large float clearances freely exhaust or admits air during pipeline filling or draining.
During normal pipeline operation, air accumulation and buoyancy cause the floats to lower or lift. As the water level lowers inside the valve, small amounts of accumulated air are released through the small orifice.
Once air is released, the float poppet closes drip tight. Valve servicing is easy because the entire float system can be replaced without removal of the body.
