Stainless Steel SRVH-S-6-N | 3/8 in. OD, No Spring, Buna-N O-Ring, 6000 psi High Pressure Relief Valve

The SRVH-S-6-N is a 3/8" OD high-pressure relief valve engineered for safety-critical fluid and gas systems. Made from corrosion-resistant 316 stainless steel, this valve features a Buna-N O-ring for chemical sealing and delivers adjustable cracking pressure from 225 to 6000 PSIG—ideal for dynamic high-pressure environments where controlled venting is essential.

With no internal spring, it maintains precise control over relief thresholds and is equipped with lock wire features to secure the pressure setting in the field. Its compact design integrates cleanly into OEM instrumentation, chemical processing lines, and sanitary systems requiring dependable overpressure protection.

Fully compatible with Swagelok® style fittings, the SRVH-S-6-N is a go-to solution for engineers designing high-purity, high-risk environments where performance and safety can’t be compromised.
