China Multi Circuit Protection Valve Suppliers

A multi-circuit protection valve is provided for a vehicle compressed-air supply device. A first port for a service brake includes two mutually separate service brake circuit ports for a first service brake circuit and a second service brake circuit. The two service brake circuit ports are protected by first and second service brake circuit overflow valves, respectively. A second port for a parking brake, is protected by an overflow valve, wherein one of the two service brake circuits can be filled preferentially. The overflow valve has two active surfaces which can be acted on with a valve inlet pressure and a valve outlet pressure, respectively. The overflow valve has a third active surface, which is acted on with the service brake pressure from the non-preferentially filled service brake circuit. Forces generated by the three active surfaces counteract a closing force in order to open or hold open the overflow valve.
