Tectran Air Brake Bobtail Proportioning Relay Valve

Achieve optimal braking performance during bobtail operation with the Tectran Air Brake Bobtail Proportioning Relay Valve. This innovative valve acts as a two-in-one solution, combining a standard service brake relay valve with a dedicated bobtail proportioning valve within a single housing. The lower portion functions as a standard service brake relay valve, ensuring efficient application and release of braking pressure while the upper portion houses the bobtail proportioning valve, which automatically reduces service brake application pressure whenever the vehicle is not towing a trailer (bobtail operation). This ensures proper brake feel and minimizes unnecessary wear on the brakes during solo journeys. The Tectran TV065146 comes complete with a convenient mounting bracket for a hassle-free installation process.
