■ GDC-JQelectro high vacuum butterfly valve uses electromagnetic force to directly drive valve disc working. thus to make valve opened ro closed. 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.
