What does an exhaust brake valve do?

This exhaust brake valve functions as a vital part of the engine braking system, specifically engineered for heavy commercial vehicle applications. By restricting the flow of exhaust gases, it enables compression braking to assist in vehicle deceleration, reducing the load on the primary service brakes and enhancing overall safety during descent or heavy hauling.

It is also compatible with other heavy commercial vehicle fleets requiring precise engine management.

Installation and maintenance

For workshop technicians and fleet managers, ensuring proper installation is key to maintaining system integrity. This valve should be inspected alongside the exhaust manifold and turbocharger connections to prevent leaks.
