Solutions to common failures of pneumatic actuators

The fault solution of the pneumatic actuator will be to select a more appropriate pneumatic actuator, and the pneumatic actuator has a higher cost performance, then we need to understand the type of the actuator, the actuator can be divided into pneumatic actuator and electric actuator, the more commonly used actuator is these two types, we will usually choose the pneumatic actuator.

So we need to select the actuator according to the size of the air source, and can not understand the torque required to rotate the valve. If the valve is too large, the valve will not last long. Usually, with 30% torque allowed, the pneumatic actuator is operated by air. Compared with the electric actuator, it can adapt to more environment, its reasonable structure makes its load greater, to achieve the purpose of high torque output. Together, compared with the electric actuator, the action is faster and the response is faster. Of course, the electric actuator also has many incomparable advantages over the pneumatic actuator. Pneumatic actuators also have advantages that current electric actuators do not. Both of them have their own flaws and strengths. Therefore, under the continuous development of science and technology in the future, the cost benefit of both will be greatly improved.

Secondly, we evaluate the platform of the equipment, select the actuator for each environment, the actuator has a specification, we will find the corresponding specification according to the valve is correct. As a pneumatic actuator, its role in the valve is to make the valve equipment more convenient to use. Because of the connection of the pneumatic actuator, the valve can drive the valve body parts to move quickly when running in the pipeline, and has a certain automatic effect. In addition, because the actuator itself is energy driven, it has certain value to drive the open and closed parts of the valve body. This valve is used in fluid lines for opening and closing because of its low fluid resistance.
