Pilot Operated Safety Valve

Nominal Diameter: DN15-200; 1/2”~8”
Nominal Pressure:PN10~100; 150LB~1500LB
Material: Carbon Steel, Stainless Steel etc.

Pilot Operated Relief Valves are used for emergency relief during over pressure events (e.g., a tank gets too hot and the expanding fluid increases the pressure to dangerous levels). As safe protected devices, it is to be used in equipment and pipeline systems of air and petroleum gas that which operation temperature is no higher than 420℃. When the pressure in equipment or pipeline exceeds allowed value, the valve will be opened automatically and fully discharge, then closed again when the pressure reduced to the regulated value so as to ensure the safe operation of the equipment or pipeline.
