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;

 

 

 

 

 

 

 

 

 

 

 

 

  Single acting wafer type ball valve:

 

 

 

Single acting pneumatic actuator working principle:

 

  1. Compressed air access into A hole, then the piston will be separates;
  2. Spring will be stressed, so that the drive shaft anticlockwise, valve open;
  3. Air remove from the B hole;

1.  Air remove from the A hole;

2.  Compression spring moves the pistons closer;

3.  Driven shaft clockwise;

4.  Air into from the B hole;
