Smart HD Exhaust Flaps

Exhaust Flap for Commercial Vehicles

Exhaust flaps for commercial vehicles must be able to resist higher vibration and pressure loads. Commercial vehicle exhaust flaps are also used for a range of different functions: for example, in thermal management, exhaust gas recirculation, braking assistance, or shift assist in automatic transmissions. When it comes to actuators for exhaust flaps, we differentiate between smart and non-smart options.

Smart HD Exhaust Flaps

Smart HD exhaust flaps or back-pressure valves (BPV) are available with various flange solutions for tube diameters of up to 120 mm. Due to the high vibration loads, the actuators installed are decoupled from the flap housing. The control functions are performed by a smart heavy duty actuator that communicates with the engine control unit via a CAN signal. Electrical connections are made with either an integrated connector or a pigtail cable solution. A software layer allows the configuration of special service functions.
