Waste gas door control valves Waste gas door control valves as a proportion tee electromechanical electromagnetic valve, adjust the ECM pulse width can realize in any case the precise booster control. This device is equivalent to a single class pressure regulator, used in the waste gas door the implementation of the pressure power control. The pressure sensor to the ECM feedback information, provide
