Three stage pneumatic actuator

三段式氣動執行器

The three-stage pneumatic actuator includes: 0 ° -45 ° -90 ° and 0 ° -90 ° -180 °. At port 2, after intake, the piston moves towards both ends and is mechanically limited by the auxiliary pistons at both ends to achieve the middle position. Two end adjustment can be used, such as 20 °, 30 °, 50 °, 75 °, 95 °, 120 °, 130 °, 150 °, 175 °, etc. Three stage pneumatic actuators are mainly used for quantitative loading and quantitative canning systems to achieve segmented control of the controlled ball valves.
