Pilot Operated Pressure Relief Valve

Product Description

We are offering here the Pilot Operated Pressure Relief Valve is used for emergency relief during overpressure events (e.g., a tank gets too hot and the expanding fluid increases the pressure to dangerous levels). It has the same function as a direct-acting relief valve; however, it has a different pressure vs. flow curve. It is a mechanical indicator, available only for modulating pilots, allowing for the accurate verification of set pressure. The Pilot Operated Pressure Relief Valve is very efficient and useful.
