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.
