The TBC Valve is mounted on the trailer reservoir and reacts to a signal from the trailer supply line to charge the tank and to control the spring brake section of double diaphragm spring brakes to provide parking and emergency braking.
The Haldex Trailer Brake Control Valve is lightweight and capable of withstanding high impact. It's also resistant to corrosion and chemicals. An exhaust cover keeps road dirt and grime out, and inlet filters help eliminate system contamination and promote long service life
Internal pressure protection and check functions isolate reservoir failures to prevent automatic application of the trailer spring brakes.
The valve is available in either Service Brake Priority or Spring Brake Priority.
