The ISF1 series control valve is an electronic pressure regulator designed to precisely and proportionally control the pressure of gases based on an electronic signal.

The ISF1 operates using two normally closed solenoid valves, a pressure sensor and a control circuit. One valve is actuated to allow unregulated supply media into the system. The second valve is actuated to allow working media to vent to atmosphere. The pressure sensor provides feedback to the control circuit. The control circuit compares the pressure sensor feedback to the user supplied electronic command signal and actuates the appropriate valve until the two signals match.

The ISF1 series can be teamed with a variety of

one-to-one pressure volume boosters for even greater flow.
