IRV - Industrial Relief Valve

Intended for pressure relief of industrial piping and system sections against excessive pressure.

Suitable for industrial gas and liquid applications subject to correct sizing and media compatibility.

Set pressure range: 0.69 to 51.7 bar.

Permissible operating temperature: -196 °C to +190 °C, depending on seal material.

Product overview: Industrial brass pressure relief valve, 1/4" to 1/2" NPT, set pressure range 0.69 to 51.7 bar.

Function: Spring-loaded pressure relief valve for overpressure protection in industrial systems. Seat and poppet geometry combined with optimized spring ranges provide high flow with minimal pressure accumulation.

Media: Suitable for industrial gas and liquid applications subject to correct sizing and media compatibility.

Factory setting / testing: Factory preset, 100% tested for leakage, crack pressure and reseat performance; set pressure secured against adjustment. Field adjustment of the relief pressure is not intended.

Oxygen service: Optionally cleaned and packaged for oxygen service in accordance with CGA G-4.1.

Seals: FKM and fluorosilicone for 0.69 to 51.7 bar; PTFE and PCTFE for 3.45 to 51.7 bar. Optional PTFE seals are specified for severe-service applications and set pressures above 3.45 bar.

Permissible operating temperature: -196 °C to +190 °C, depending on seal material.

Inlet: 1/4", 3/8" or 1/2" NPT connection.

Outlet: Vent to atmosphere, deflector cap for directing exhausted gas, or inline/pipe-away connection to downstream piping, depending on configuration.
