Introduction
GDC-J electro high vacuum flapper valve is powered by electromagnetic force to drive valve disc directly, thus to make the valve open or close. It is applicable for vacuum system to cut off or put through the airflow. When valve is closed, and there is atmospheric pressure above the sealing face and vacuum below the sealing face, here the sealing effect is the best. Applicable medium can be pure air and noncorrosive gases.
