4.3.3 

Double-Acting Actuators

The operating principle, as explained here, is applicable for actuators with assembly code 
CW (direct acting).

• 

Applying supply pressure to port A will move the pistons outward to the "Open" 
position of the valve.

• 

Applying supply pressure to port B will move the pistons inward to the "Close" 
position of the valve.

• 

For assembly codes CC, the operating principle is reversed (reverse acting).
