Valves

Control of the auxiliary braking system The engine brake is an important auxiliary braking system in heavy trucks, intended to relieve the service brakes during long descents. The febi valve for the engine brake is the control element that activates this system. It controls the airflow needed to engage the engine's braking action. Dependable operation and fit A leaking or poorly responding valve can make the engine brake function unreliable. The febi valves are OE-compliant and therefore fit precisely on the original connections. This provides correct operation and restores the engine's braking support, which extends the life of the brake pads and discs.
