Autorun pneumatic actuator has two kinds of models: 0°-45°-90° and 0°-90°-180°. The air intake "2" after the intake ends of the piston movement was designed to both ends there are auxiliary pistons produce mechanical constraints to achieve a middle positon, can be used directly out of both ends of the adjusting screw is easy to adjust the middle point of view, such as 20°, 30°, 50°, 75°, and 95°, 120°, 130°, 150°, 175° and so on.

Three position pneumatic actuator operation requires the design of a solenoid valve control loop system to complete the operation, the control principle as follows:

Position 1 (middle)

Air pressure at the same time and D into the two port, air from the exhaust port 4 and C, 2 as an internal piston, D mouth is by putting restrictions on secondary piston within the piston located in the middle of the booking.

Position 2 (open position)

Air pressure at the same time into 2 and the C port, air from the discharge port 4, and D, two of the internal piston to move, C auxiliary port for the lifting of restrictions on putting the piston position to reach the fully open position within the piston smoothly.

Position 3 (fully closed position)

Air pressure into 4, the air discharged from the 2, the internal piston moves to the middle reach the fully closed position. Provides 0°-45°-90° spring return position type specification, when somebody stops breathing power (or gas source failure), an internal piston back by spring force to the fully closed position.
