B series pneumatic high-vacuum butterfly valve
Unique Vacuum   Unique Vacuum
B series pneumatic high-vacuum butterfly valve uses compressed air as the dynamics. It changes the gas circuit direction, promote piston gear mechanical movement through the control of pneumatic components. The output torque pushes forward the butterfly valve to implement the open / close movements in order to connect or cut off the airflow in vacuum tubes. This is a new pneumatic controlled butterfly valve, it has Double-acting and Single -acting(Spring return) air cylinder with optional Signal feedback device and electric valves servo. The applicable active medium of this valve are air, non-corrosive gas.
