Fairchild M20BP – Pneumatic Precision Pilot-Operated Back Pressure Regulator – Rotork

Possible Applications

The Fairchild M20BP regulator is deployed in semiconductor manufacturing equipment and analytical instrumentation skids where maintaining strict upstream relief thresholds is critical to prevent process contamination or gauge failure. In chemical processing plants, it serves on gas blanketing systems and reactor purge lines to securely vent excess pressure without causing media fluctuations. Additionally, the unit is integrated into automated pneumatic test benches and calibration rigs to provide the repeatable relief performance required during high-precision sensor testing.
