Double acting wafer type Ball valve:

 

•  Anticlockwise                                      •  Clockwise      

 

 

 

 

 

Double acting pneumatic actuator working principle:

  1. Compressed air access into A holes, then the piston separates;
  2. So that the drive shaft anticlockwise, valve open;
  3. Air remove from B hole;

 1.    Compressed air access into B holes,  

        then the piston will be closer;

2.     So that the drive shaft clockwise, valve close;

3.     Air remove from A hole;
