Differential pressure relief valve
Differential pressure relief valve
Use and operation:
This relief valve provides fast and accurate overload protection: when it reaches the pressure setting value, the valve opens the decompression function in order to prevent the pressure from exceeding this setting value. This differential pressure relief valve opens the decompression function slower than the standard relief valve, but the spring setting value is more stable when the pressure flow changes.
Application:
Connect the circuit port to pressure P and the tank port to pressure T. Specification 1″ is provided for double oil outlet T (oil outlet 1 can be covered and sealed according to installation needs).
