DZ93189360013 DZ95259360105 Original Shacman Heavy Truck Relay Valve With Connector

The air inlet of the relay valve is connected to the air reservoir, and the air outlet is connected to the brake chamber. When the brake pedal is pressed, the output air pressure of the brake valve serves as the control pressure input of the relay valve. Under the control pressure, the intake valve is pushed open, and compressed air enters the brake chamber directly through the intake port from the air reservoir, without passing through the brake valve. This greatly shortens the inflation pipeline of the brake chamber and accelerates the inflation process of the chamber. Therefore, the relay valve is also known as the acceleration valve. The relay valve is used at the end of a long pipeline to quickly fill the brake chamber with compressed air from the air reservoir, as in the braking system of a trailer or semi-trailer. Generally, differential relay valves are used. To prevent the simultaneous operation of the driving and parking systems, as well as the overlap of forces in the combined spring brake cylinder and spring brake chamber, thereby avoiding overloading of mechanical transmission components that can quickly charge and exhaust the spring brake cylinder.
