GH22/42 Series Ratio or Flow Boosting Relay

Flow Boosting Relay
The Conoflow GH22/42 Series Flow Boosting 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.
