Pneumatic 2:1 Ratio Amplifying Relay

Pneumatic 2:1 Ratio Amplifying Relay is a proportional device designed for use in pneumatic control systems where the application requires the amplification of a proportional signal from a controlling device. The relay’s branch line pressure output increases as a 2:1 ratio to the input signal pressure (up to main air pressure) and amplifies the volume of air available to the final control device, thereby minimizing system lag.
