Twin Piston Pneumatic Piston Actuator , Three Stage Air Piston Actuator
Three Stage style actuator is special kind of actuator with 3 stage (0°,45°,90°or 0°,90°,180°). The middle position can be reached by mechanical movement of two auxiliary pistons and can be adjusted. For example, the 90°actuator can have middle positions of 20°,30°,50°,70°.
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.
