First, GIQ high vacuum pneumatic butterfly valve overview:

The pneumatic actuator of GIQ series pneumatic vacuum butterfly valve is powered by compressed air. The electromagnetic reversing valve changes the direction of the gas path, pushes the mechanical movement of the piston rack and pinion, and drives the butterfly valve with angular output torque to open and close the movement. Thereby the purpose of turning on or off the air flow in the vacuum line is achieved. Pneumatic vacuum butterfly valve is a new type of pneumatic actuator controlled pneumatic vacuum butterfly valve, which is divided into double-acting and single-acting (spring-return) cylinders. The pneumatic vacuum butterfly valve can be equipped with a feedback signal device and an electric valve positioner. The working medium for pneumatic vacuum butterfly valves is air and non-corrosive gases.

Second, the main features of vacuum pneumatic butterfly valve:

1. The valve can withstand positive pressure

2. The valve stem does not move up and down;

3. Pneumatic vacuum butterfly valve cylinder adopts 1/4 rotary cylinder, the angle can be adjusted from 1 ° to 5 °.

Third, the implementation standards of high vacuum pneumatic butterfly valve:

 
Fourth, the main parameters of the pneumatic actuator:
