Frequently Asked Questions

What is the difference between PSV and PRV?

PSV (pressure safety valve) opens rapidly at set pressure for compressible fluids. PRV (pressure reducing valve) modulates to hold a lower downstream pressure. Supreme Valves supplies both.

What API standards apply to PSV?

API 520 for sizing, API 526 for design, API 527 for seat tightness testing.

Do you supply IBR-certified PSV for boilers?

Yes. Spring-loaded PSV for boiler drum, superheater, and economizer with IBR Form III-C and inspector stamp.
