The three-stage pneumatic actuator is a special type of actuator, which can provide three-position operation modes of 0°, 45°, 90°, and 180°. The intermediate position is achieved by the mechanical brake produced by the movement of the two auxiliary pistons. The intermediate position is adjustable.

Discription

Three Position Design Pneumatic Actuator is a special type of actuator, which can provide three-position operation modes of 0°, 45°, 90°, and 180°. The intermediate position is achieved by the mechanical brake produced by the movement of the two auxiliary pistons. The intermediate position is adjustable. For example, the actuator with 90° stroke can provide intermediate positions of 20°, 30°, 50°, 70° and so on.
