What is in the PSV technical datasheet PDF?
The Pressure Safety Valve Technical Datasheet PDF (Doc. SV-DATA-2026-PRESSURE_SAFETY_VALVE) is the reference buyers and engineers use to check orifice, set pressure, materials and test requirements before RFQ. It covers spring-loaded PSVs for steam, gas and liquid overpressure protection.
- Design / testing: API 526 / ASME Section VIII (as applicable), API 598 / EN 12266 shell and seat tests
- Typical sizes: DN15 to DN150 (½" to 6") inlet × outlet combinations
- Pressure class: PN16 / PN25 and ASME Class 150 / 300 (higher on request)
- Body: ASTM A216 WCB; nozzle and disc in SS410 / SS316 / CF8M
- Spring: Cr-Va alloy spring steel (EN-47)
- Certificates: EN 10204 3.1 MTC standard; 3.2 / TPI on request
Key specifications (from the datasheet and catalogue)
How to RFQ against this datasheet
- Fluid (steam / gas / liquid), molecular weight or specific gravity if known

Frequently asked questions
Where can I download the PSV technical datasheet PDF?
Use the orange Download PDF button on this page, or open https://www.supremevalves.in/datasheets/pressure-safety-valve-datasheet.pdf. Doc. SV-DATA-2026-PRESSURE_SAFETY_VALVE, about 775 KB.
What is the difference between a PSV and a PRV?
A PSV (pressure safety valve) is typically for compressible fluids and opens fully at set pressure. A PRV (pressure reducing valve) controls downstream pressure in normal operation. This datasheet covers safety / relief valves.
What sizes and ratings are covered?
DN15 to DN150, PN16/PN25 and ASME Class 150/300 as standard; higher ratings on enquiry.
Which materials are listed?
WCB body with SS410/SS316 nozzle and disc as standard. SS304, SS316, WC6 and LCB bodies are available from the manufacturer range.
Is the datasheet free?
Yes. No registration required.
Can you size the orifice for my duty?
Yes. Send fluid, set pressure, capacity and temperature and we return orifice letter, datasheet and price.
