About Relief Valves
Valorex Global Relief Valves are externally adjustable, spring-loaded safety valves that open automatically when system pressure exceeds the set-point and reseat when pressure drops back to safe levels. The external adjustment mechanism allows set-point changes without valve removal, and the lock wire facility prevents unauthorised adjustment or tampering. Two orifice sizes (3.6mm and 4.8mm) allow selection for different flow capacities. The high-pressure 15K range serves hydraulic testing, subsea and wellhead applications where conventional relief valves are insufficient.
