F627 High Flow Gas Regulator The F627 pilot operated pressure reducing regulator provides superior performance when used in pressure-factor measurement (fixed-factor billing) applications. The Type F627 includes a factory-installed pilot and has external registration that requires a downstream control line. Features • Accurate for Pressure-Factor Measurement Applications — Pilot action controls pressure to within ±1 percent of the absolute outlet pressure (PSIA) setting at full travel. This capability results in low-pressure variations over broad flow ranges and inlet pressure ranges. • Wide Range of Flow Capabilities — A variety of body and orifice sizes are available. • Tight Shutoff Capability — A flat disk of nitrile provides excellent shutoff capability.
