what is the Relay Valve?


The relay valve is part of an automotive airbrake brake system. In a brake system of a truck, the relay valve functions to shorten the reaction time and pressure build-up time.

The air inlet of the relay valve is switched on and the air outlet is connected to the brake air chamber. When the brake pedal is depressed, the output pressure of the brake valve is used as the control pressure input of the relay valve. Under the control pressure, the intake valve is pushed open, and the compressed air is directly entered by the air reservoir through the air inlet. The plenum chamber does not have to flow through the brake valve, which greatly shortens the inflation circuit of the brake chamber and accelerates the inflation process of the chamber. Therefore, the relay valve is also called an accelerator valve.

The relay valve is used at the end of a long pipeline to quickly fill the brake cylinder with compressed air, such as in a trailer or semi-trailer brake system.

To prevent the simultaneous operation of the traveling and parking system, the overlap of the force in the combined spring brake cylinder and the spring brake chamber, so as to prevent the mechanical brake element from being overloaded to rapidly charge and exhaust the spring brake cylinder.
