Double acting 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;
