EGR Valve: Description and Operation
Electric Exhaust Gas Recirculation (EEGR) Valve
EEGR Motor/Valve Assembly
Depending on the application, the EEGR valve is a water cooled or an air cooled motor/valve assembly. The motor is commanded to move in 52
discrete steps as it acts directly on the EEGR valve. The position of the valve determines the rate of EGR. The built-in spring works to close the valve
(against the motor opening force).
