CLAYTON Pressure sustaining valve


A CLAYTON Pressure sustaining valve can perform two functions.

Pressure holding function: The CLAYTON Pressure sustaining valve maintains the set inlet pressure at a constant level regardless of flow fluctuations.
Pressure release function: The CLAYTON Pressure sustaining valve protects the mains on the inlet side and relieves any possible overpressure to the atmosphere.

Minimum inlet pressure 0.2 bar, minimum differential pressure 0.5 bar.
