Fixed-Set Safety Valves
Fixed-Pressure Safety Valve
A fixed-pressure safety valve is a spring-loaded safety valve with an opening pressure set and sealed at the factory that cannot be adjusted in the field. With no risk of accidental adjustment changes, it provides safe protection in heating boilers, combi boilers, solar energy systems and hot water tanks.
Supplied with brass body, steel spring and NBR seal in sizes from 1/4″ to 1 1/2″, available in male or male-female threaded connection. Select according to your system’s requirements with different fixed opening pressures (for example 3, 6 or 9 bar).
