GH22 Series Ratio or Flow Boosting Relay

Brand: ITT Conoflow
Request Information

The Conoflow GH22 Series Relay is used to boost, amplify or reduce the pneumatic signal of a controller or similar instrument in a predetermined ratio.

Using an independent supply pressure for greater flow volume, the unit relays an instrument signal to a final control element such as a valve actuator.
