3-position Pneumatic Actuator
Two types of 3-position pneumatic actuators:0°-45°-90° type and
0°-90°-180° 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°,1 20°,1 30°,150°,1 75°etc by
using the adjusting screws at each end of the surface.
