Application Notes The C-2 Relay Valve functions to reproduce in substantial volume whatever pressure is applied to the small volume control portion of the valve itself. Its essential purpose is to increase the speed of operation for devices such as brakes, clutches, positioning devices and to reduce transmission time in control lines. This valve is usually directed by a relatively small pressure control valve, such as a CONTROLAIRâ„¢ Valve, which is located at some distance from the controlled volume and is connected by small diameter pipe or tubing.
Application Reproduces pressure from control line independent of leakage or temperature effects.
