Frequently Asked Questions — Pressure Safety / Relief Valve
Common technical questions from enquiries we receive, answered by Supreme Valves India.
What is the difference between a PSV and PRV?
A Pressure Safety Valve (PSV) opens rapidly (pop action) for gas/vapour overpressure protection. A Pressure Relief Valve (PRV) opens proportionally and is used for liquid overpressure service. Both are used to protect vessels and piping.
What standards govern safety valves?
API 520/521 for sizing and selection, API 526 for flanged steel PRVs, API 527 for seat tightness, and ASME Section I/VIII for code requirements.
What specifications are commonly enquired for Pressure Safety / Relief Valve?
Customers frequently enquire for: 1346-543, 2763, 304, 526, 6" x 8, 835, API 526, 000, 001, 15NB, 200, 2026. We can accommodate custom specifications — please share your datasheet or line list for a detailed technical quotation.
