High Vacuum Butterfly Valve
pneumatic
high vacuum butterfly valve uses solenoid directional valve to change the
direction of air passage, and controls the actuating cylinder to drive the
butterfly valve opened and closed. It is used to put through or cut off the
airflow in vacuum pileline. Applicable medium can be pure air and noncorrosive
gases. They may be fitted with signal feedback device and electropneumatic
valve
