⚡ Direct vs Pilot-Operated Regulators (2-5 PSI to 7"-14" WC), Lockup & Droop

Commercial Gas Pressure Regulator Calculator

Size commercial industrial natural gas and propane pressure reduction regulators (Fisher / Sensus / Pietro Fiorentini): calculate maximum flow capacity (SCFH based on inlet pressure, outlet setpoint, and orifice diameter), lockup pressure over-boost limits, proportional droop percentage, vent piping, and mechanical plumbing margins.

1. Project & Operating Inputs

Peak Downstream Gas Demand (SCFH e.g. 4,500 SCFH)

Inlet Utility Gas Supply Pressure (PSIG e.g. 5.0 PSIG Supply)
