What Is a Piston Actuator?

Source: In order to fully use the air source pressure of the factory to increase the output force of the actuator and reduce its weight and size, a piston actuator was produced.

Piston actuator

Right!

Source: In order to fully use the air source pressure of the factory to increase the output force of the actuator and reduce its weight and size, a piston actuator was produced.

Due to the influence of traditional applications, the application of piston actuators is limited to large thrust, so there are fewer applications. This is because in the past, the pressure of the positioning gas source was 140 ~ 250KPa, and the positioner of the 700KPa gas source had poor reliability. Today, this problem no longer exists, and the pressure of 700KPa or more for the positioner can be achieved by one positioner. In other words, the current positioner can be used in both 140 ~ 250KPa and 700KPa occasions. In this way, we should change the traditional practice. Select a 700KPa air source positioner and replace it with a piston actuator The film actuator reduces the size and weight of the pneumatic control valve, so it can be predicted that the application of the pneumatic piston control valve will become more and more widespread.
