Belgas F289 Type Back Pressure Regulator Relief Valve

Belgas Type F289 Pilot-Operated Back-Pressure Regulator

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 Pilot-Operated Back Pressure Regulator

The pilot regulator allows accurate back-pressure control with minimal buildup over the set pressure for the main valve’s full opening. The F289 serves in applications of fuel gas relief and gas gathering relief.
