Pneumatic high vacuum butterfly valves
GIQ-B/AB series high vacuum pneumatic butterfly valve is drived by compressed air, through the pneumatic device to change the direction of gas, and control the implementation of the cylinder to drive the butterfly valve, connect or disconnect the airflow of vacuum tubes. The applicable medium is air and non-corrosive gas. Note:GIQ-B/AB actuator: optional feedback signal device.
