GH22 Series Ratio or Flow Boosting Relay

GH22 Series Ratio or Flow Boosting Relay
Product Description

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.
