Pneumatic multi-position actuators are available with two different functional principles. According to the first principle, multi-position actuators consist of two separate cylinders which are connected together by a kit and have piston rods that extend in the opposite direction. Depending on the control and stroke distribution, this cylinder type can therefore assume up to four positions. According to the second principle, multi stage pneumatic cylinders consist of two to five cylinders connected in series with different stroke lengths. With this cylinder type, only one piston rod is visible, which moves to different positions in one direction.
