Description of Pressure Relief Valve 50B-4KG1

The Cla-Val Model 50B-4KG1 (Globe) / 2050B-4KG1 (Angle) Pressure Relief Valve is designed specifically to automatically relieve excess pressure in fire protection systems. This pilot controlled relief valve maintains constant system pressure at the pump discharge within very close limits as demands change. Operation is completely automatic and pressure settings may be easily changed. This valve can be used for pressure relief, pressure sustaining, back pressure, or unloading functions in a bypass system. This fast opening, slow closing relief valve provide system protection against high pressure surges on pump startup and pump shut down by dissipating the excess pressure to a safe location.
