What is The Trailer Control Valve

Date:2022-11-10
A trailer control valve can prevent the trailer from swerving. When you apply the parking brake, the valve opens, creating pressure in the brake line and moving the trailer into a brake position. When you release the brake, the trailer moves back into park position. You must ensure that you have the right trailer control valve installed.
A trailer control valve has a valve actuating piston, which is associated with a pneumatic control circuit. The valve switches between open and closed states when a pressure increase or decrease is detected. It is connected to the trailer's pneumatic control circuit by a reservoir line 68. It also has a control input 59 that is associated with an electrical or pneumatic control circuit.
A trailer control valve typically includes two parts: a control chamber and a control piston. The control chamber houses a valve that communicates with a pneumatic circuit that is associated with an auxiliary brake system. The valve can also be associated with a service brake system and communicates with its electrical control circuit via a pneumatic link.
A trailer control valve is the most important safety component in a trailer. In order to keep the trailer and vehicle safe, it needs to be designed to handle the trailer's brake pressure.
