Skip the test bench. Get a Swagelok relief valve precision-set to your set pressure on a calibrated nitrogen test bench, locked, and tagged with the set pressure.
We set, test, and tag each valve so you don’t have to. Because we do this locally, you can get the components you need fast.
Each valve is:
Set pressure adjusted on a calibrated nitrogen test bench.
Locked in place so the setting cannot drift during handling or installation.
Matched to your fluid, temperature, and pressure range.
Tagged with a stainless steel ID tag that’s stamped with the set pressure and date, so you never have to search for it.
Set, Locked, and Ready to Install.
Swagelok’s relief valve product offerings cover the full pressure range from low-pressure venting to high-pressure applications. Our team helps you select the right parts and provide a custom configuration for each valve based on your set pressure, fluid, and connection.
Material compatibility: Extensive seal options to withstand your specific fluids and environmental conditions.
Specialized cleaning: Available in high-purity and UHP configurations, with certifications for low-emission API compliance.
Identification: Stainless steel ID tag stamped with set pressure and the date the valve was set.
PROPORTIONAL RELIEF VALVES - R-SERIES
The R Series is the workhorse for general industrial overpressure protection. Valves open gradually as pressure rises and reseat when system pressure falls below the set point. Used in most plant air, gas, and liquid service applications.
ADJUSTABLE RELIEF VALVES - RV SERIES
RV Series Medium and High-Pressure Adjustable Valves cover the pressure ranges where R Series tops out. Two spring ranges handle medium- to ultra-high-pressure applications common in research, hydrogen, and high-pressure gas systems.
PROPORTIONAL SAFETY-RELIEF VALVES - PRV SERIES
PRV Series valves are certified safety-relief valves. Five spring pressure ranges cover the most common process set points, with each valve factory-set, tested, locked, and tagged at Swagelok before shipment. PRV is the right choice when you need certification documentation alongside the physical valve.
Configuration Options for Every Valve
Body Materials: 316 stainless steel standard; alloy options available for corrosive or NACE service standards.
Seal Materials: FKM, Buna-N, Neoprene, EPDM, and Kalrez - matched to your fluid and temperature.
End Connections: Swagelok tube fittings, NPT, ISO, and pipe weld in standard sizes.
