More Information
Summary:A trailer control valve having control pistons for actuating a double seat valve, which can control the communication between a compressed air reservoir, a compressed air consumer, and a pressure relief location. In order to structurally simplify the trailer control valve, a control piston is provided that is jointly associated with an electrical control circuit and a pneumatic control circuit of a service brake system. Furthermore, a valve is provided that is connected to the pneumatic control circuit of the service brake system, which closes the pneumatic control circuit of the service brake off from to the trailer control valve when the electrical control circuit is functional, and in the event of a failure of the electrical control circuit, unblocks the pneumatic control circuit of the service brake system.
