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.

Sourcing
Don't see the exact unit? We source it.
Send the model, size or nameplate details. We check our dealer, factory and surplus network and quote price and lead time within 24–48 hours.
What does 'rebuilt' mean at DWP?
A rebuilt unit has been disassembled, inspected, had worn parts replaced and been tested before it goes on the shelf. It is covered by the same 30-day return policy as everything else we ship. 'Used' means as removed from service: we photograph the nameplate and note the condition, but the unit has not been through the shop.
Can I order with a PO or tax-exempt?
Yes. Purchase orders and tax-exempt certificates are accepted. Request a quote with the unit and quantity, and we return a formal quote your procurement team can attach to the PO.
What if the unit I need isn't listed?
Tell us the model, size and what it does. We source through a dealer, factory and surplus network and quote price and lead time within 24–48 hours. That includes obsolete and discontinued equipment.
