Pressure Relief Valves

Pressure Relief Valves

A pressure relief valve lifts at a set pressure to vent excess and reseats when the system recovers; it is the last line of protection on boilers, receivers and process vessels. DWP receives relief and safety valves in plant storeroom lots and they move quickly, so this collection is thin between lots. Listed now is a Varec 3500 series 10 inch vacuum relief valve for tank breathing service.

To source one, request a quote with the set pressure, inlet and outlet size and class, body and trim material, and the code stamp you need (ASME Section I or VIII). Answers within 24 to 48 hours; the 30-day money-back guarantee applies.
