3-position Pneumatic Actuator

Two types of 3-position pneumatic actuators can be provided, namely 0°-45°-90 °type and 0°-90°-1 80°type

respectively. After the air comes into the cylinder from the air entrance ” 2 ” , the pistons’ movements toward the ends would be limited by the auxiliary pistons mechanism. Thus the pistons would stay in the middle position.

The position of the mid position could be adjust to 20 °,30°,50°,75°and 95°,120°,130°,150°,175° etc by using the adjusting screws at each end of the surface.
