Back Pressure Regulator/Relief Valve

The Back Pressure Regulator/Relief Valve (BPRV) maintains constant pressure and constant analyzer flow while protecting critical sampling components as a relief valve.

Standard pressure setting: 20 psig (1.4 barg), other pressure settings available.

• Precise pressure reduction and control when used in conjunction with a VREL® or needle valve
• Most effective way to assure a constant flow rate to on-line analyzers
• Specially designed for steam/water sampling service 
• Non-plugging design
• Will not wire draw or erode in normal service
• Fail safe relief valve
