CompAct Actuators Configurations
The actuator can be configured for either spring return or double-action operation. In both
cases the air supply to drive the pistons flows into Port A of the NAMUR cover. Port A is
connected to the center chamber, and Port B is connected to the four outside chambers.

Pressure exiting Port A to close:
• Center chamber is pressurized and
pistons move outward
• Air released from center chamber
• Springs are compressed
• Pinion rotates clockwise
• Springs drive pistons inward
• Pinion rotates counterclockwise
