Cummins 5667524 Exhaust Throttle Valve Assembly

The Cummins 5667524 exhaust throttle valve assembly is engineered for the ISF2.8 and ISF3.8 engine series. It integrates an electronic actuator to modulate exhaust flow, enabling exhaust gas recirculation (EGR) control and engine braking functionality. The valve body is constructed from high-temperature austenitic stainless steel to withstand thermal cycling and corrosive exhaust gas constituents. The actuator module operates on 24V DC vehicle system voltage with PWM signal control from the engine ECU. This component is a direct replacement for Cummins part numbers 5604882, 5548693, 5496372, and Bosch A2C19225900. It is calibrated for Foton Aumark (S1, S3, S5, CTX, CTS), Omakai, Rowor (E3, ES3), and Era series light and medium-duty commercial vehicles. Installation requires torque-to-yield fasteners and ECU adaptation reset via diagnostic tool. Service interval aligns with major engine overhaul or upon fault code activation for exhaust pressure deviation.
