Double Acting Pneumatic Actuator AT-D

The Double Acting pneumatic actuator controls the valve by the gear shaft rotating movement, which is driven by the meshing movement of the rack and the gear by the piston.

When the pressure of the air source enters the middle cavity between the two pistons of the cylinder from the air port, the two pistons are separated and moved toward the two ends of the cylinder, and the air in the air chambers at both ends is discharged through the air port, and the two piston racks simultaneously drive the output shaft (gear) Turn counterclockwise. Conversely, when the pressure of the air source enters the air chambers at both ends of the cylinder from the air port, the two pistons are moved toward the middle of the cylinder, and the air in the middle air chamber is discharged through the air port. At the same time, the two piston racks synchronously drive the output shaft to rotate clockwise.
