Two additional pistons make a third (intermediate) position
possible. The intermediate position is exactly reproducible. To use
for multiple-way valves and pig valves. Safety function with
spring-centered central position
pneumatic twin piston actuator, single-acting and double-acting
version with two additional pistons, pivoting angle 90°+ 90° (180°)
respectively 120°+ 120° (240°)
valve combinations (preferably 3/2-way) corresponding safety
conception respectively requirements.

Principle of Single Acting Actuator (Spring Return)
CCW
Air to port A forces the pistons outwards, causing the springs to
compress, The pinion turns counterclockwise while air is being
exhausted from port B.
Loss of air pressure on port A, the stored energy in the springs
forces the pistons inwards. The pinion turns clockwise while air is
being exhausted from port A.

Principle of Double Acting Actuator
