There are three main types of
trailer control valves. The first type is called a shut-off valve, and is located in the service or supply air lines on the back of the trailer. When not in use, shut-off valves allow air lines to be closed. Once you stop towing, close the valve before you start pulling the next trailer.
The other type is called a relay valve. It functions similarly to a transistor in an electronic circuit. It allows the service brake to work even if the tractor's braking system fails. The service brake is controlled by the pressure in the service line. To keep the valve working correctly, it must be cleaned regularly.
The trailer control valve is a critical piece of equipment in the trailer. If it doesn't work properly, you'll be left with a poorly functioning trailer. A malfunction in the valve can cause your trailer to become immobile and unsafe to drive. It is important to know that you're getting the right trailer control valve for your needs.
To rapidly increase or decrease the pressure of compressed air equipment and to shorten the response and pressure build-up times in air braking systems.
Features and Innovation
---Relay valves for service brake and parking brake applications shortens brake response times
---Integrated check valves for parking brake applications.
---Relay valves with load control can adjust the front axle brake pressure to vehicle loads.
---Overload protection valves help prevent addition of actuating forces when service and parking brake are actuated simultaneously.
Customer Value
---Better brake response times deliver shorter stopping distance.
---Quick to apply and release parking brake.
---Modular design concept enables fast installation and easier maintenance.
---Saves energy by reducing the spring-load pressure.
---Integrated check valves lower costs and shortens installation time.
---Wide portfolio of valve variants.
Application
