Back-Pressure Regulator/Relief Valve

A back pressure regulator provides steady-state control of inlet or upstream pressure. Relief valves offer reliable on/off pressure protection upon demand in systems or gas recirculation systems.

Belgas P289 back pressure regulator also functions as a relief valve with adjustable set points. A relief valve maintains pressure by redirecting higher pressure out of a pipeline. The Belgas 289 comes in three variations for different applications: the P289 is standard for high pressure, the L289 is for low pressure, and the F289 is for pilot operation.

The P63 is Belgas’ highest-capacity relief valve.

The Belgas P63 is a pilot-operated relief valve or backpressure regulator. The main valve can deliver large flow capacities while the pilot control maintains precise setpoints. The pilots have a hollow stem permitting quick loading to the top of the…

The Belgas F289 is a pilot-operated back-pressure gas regulator that operates as a high-flow relief valve with an adjustable setpoint. Use the Type F289 instead of a standard relief valve to protect against over-pressurization in the downstream system. Belgas F289…
