Humphrey ProControl™ electronic pressure regulators provide excellent closed loop control through the use of a dual proportional valve method. Analog circuits can compensate for dynamic changes in downstream pressure. Compared with competitive products, it can improve response speed, quiet operation and prolong service life.

Pilot PCRH high-flow electronic pressure regulators maintain accurate downstream pressure in dynamic upstream and downstream applications. Proportional exhaust valves eliminate the high cycle rate of open/close exhaust valves, extending product life and reducing noise. Internal valves and diaphragms provide high flow rates of 600 LPM.
