CLA-VAL 50-37 : Fast Acting Pressure Relief Valve
Cla-Val 50-37 Fast Acting Pressure Relief Valves are hydraulically operated, pilot-controlled, modulating valves designed to relieve excess pressure within close limits. In operation the valve is actuated by line pressure through a pilot control system, opening fast by discharging water from the top cover through two seperate pilot lines, to maintain steady line pressure but closing gradually to prevent surges. Operation is completely automatic and pressure settings may be easily changed.
