Double-Acting Actuators
The operating principle, as explained here, is applicable for actuators with assembly code
W (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 C, the operating principle is reversed (reverse acting).
