The Exhaust Pressure Control Valve is the DC Motor drive valve that is mounted at the rear of the DPF and the front of the LP-EGR Valve. It is the valve that recirculates the EGR gas in the required amount by controlling the pressure in front of the LP-EGR Valve. The Exhaust Pressure Control Valve is composed of the Actuator Unit that includes the valve motor and gear, and the Body that includes the housing and the valve. These two units transfer the power through coupling. In addition, the feedback position sensor is embedded so the ECM can detect the actual opening angle.
