Pressure relief valves protect equipment from overpressure. Selection requires the required relieving capacity, set pressure, backpressure conditions, and the governing code (e.g., ASME VIII for boilers/pressure vessels). Spring-loaded and pilot-operated designs suit different backpressure profiles.
Q: What is a pressure relief valve used for?
A: A pressure relief valve automatically discharges fluid when pressure exceeds a set limit, protecting pressurized equipment from overpressure.
Q: Which standards govern pressure relief valves?
A: Spring-loaded relief valves commonly follow API 526 (dimensions) and API 527 (seat tightness), with sizing per API 520 and ASME Section VIII.
Guidance reflects general engineering practice for pressure relief valves; confirm against the project specification and applicable standards before procurement.
