Series Ratio or Flow Boosting Relay

Category: Volume regulator/booster

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.

The GH22 is supplied in a brass/aluminum combination and has a maximum supply pressure rating of 200 PSI (1379 kPa). Buna “N” diaphragms are standard. Connections are 1/4” NPT. Maximum signal pressures are 150 PSI (1034 kPa) (ratio 3:1, 2:1, 1:1), 75 PSI (517 kPa) (ratio 1:2) and 50 PSI (345 kPa) for ratio 1:3.
