EGR Control Valve

The EGR control valve is used to regulate exhaust gas flow to the intake system by means of a pintle valve attached to the valve diaphragm. A ported vacuum signal and calibrated spring on one side of the diaphragm are balanced against atmospheric pressure acting on the other side of the diaphragm. As the vacuum signal applied to the valve increases, the valve is pulled further from ifs seat. The key to accurate EGR metering is the EGR vacuum modulator assembly which precisely controls the strength of the applied vacuum signal.
