CLA-VAL B50-01 : Pressure Relief Valve
Cla-Val B50-01 Pressure relief valves are hydraulically operated, pilot-controlled, modulating valves designed to relieve excess pressure within close limits. This valve can be used for pressure relief, back pressure, or unloading functions in a by-pass system. In operation, the valve is actuated by line pressure through a pilot control system, opening fast to maintain steady line pressure but closing gradually to prevent surges. Operation is completely automatic and pressure settings may be easily changed.
