When it comes to piston pneumatic actuators, the best feature of pneumatic actuators is air pressure and the best feature of compressed air is that the energy coming from the air can be stored by taking advantage of the characteristics of air in the form of pressure inside air tanks. This is especially important at the time of high-speed operations or emergency operations during power failure times. Among all different types of pneumatic actuators, the piston pneumatic actuators are becoming widely accepted and used, especially as the development of science and technology, the working processes have become more advanced and demanding. The piston pneumatic actuators can provide exceptional stiffness if there are no limitations of the diaphragm, so that they no longer have any problems with fluctuations in the process flow. Also when they ward off close to the seat, there will be enough power to prevent the close acting from being pulled into the seat. The actuator and the regulating mechanism of piston pneumatic actuators are a unified whole. Piston pneumatic actuators have quite a length, applicable to various requirements.

The working principle of the piston pneumatic actuators is as follows. When the compressed air nozzles into the pneumatic actuators from the A tube, gas will push the piston to the ends of linear motion. Then the rack piston drives the rotating shaft gear counterclockwise rotation of 90 degrees, and the valve is opened. The pneumatic gas valve ends with B nozzle discharge. Conversely, when the compressed air enters the gas from Tube B actuator ends, gas double plug to the middle line movement, and when the rack piston drives the rotating shaft gear clockwise rotation of 90 degrees, the valve is closed.

Besides, when you want to get to fully know and use a machine, you should understand its constitution. The type and structure of adjustment mechanism for the execution of the piston pneumatic actuators are roughly the same, mainly in terms of the implementing agencies. Therefore the pneumatic actuator can be divided into two parts, actuator and control valve. Pneumatic actuator control valve by the implementing agencies and the mechanism of two parts. According to the control signal size, the device generates the corresponding thrust and pushes the valve action. The regulating valve is a pneumatic actuator of the regulation in part, in the actuator thrust under the action of the regulating valve, the displacement or rotation certain, directly regulating the flow of fluid.

Here are many advantages of piston pneumatic actuators. First, they can accept the gas continuous signal, output linear displacement, some of which are with the rocker arm, which can output angle displacement. Second, it can work reversely. Third, it has a high moving speed, but when the load increases, the speed will slow down. Fourth, the reliability is high, but the interruption of gas supply valve can't keep (plus a valve can maintain). Fifth, the maintenance of piston pneumatic actuators is simple and the machine has good adaptability to environment.

To end, we are your first choice if you want to buy efficient piston electric actuators.

In order to make full use of foot plant air pressure to improve the implementation force output, reducing its weight and size mechanism produces pneumatic piston actuator.
