Product Description

                             Electric High Vacuum Butterfly Valve        
         

Electric high vacuum butterfly valve relies on the electric actuator to drive the stem and thus bring along the stem and the valve plate to make on/off movements so as to open or close the valve for the purpose of connecting or cutting off the airflow in the vacuum pipeline. The applicable media include clean air or non-corrosive gases. It is provided with a feedback signal device.
