Pneumatic valve actuator failure resolution will choose a more suitable pneumatic actuator, high cost-effective pneumatic actuator, then first we need to understand the types of actuators, actuators can be divided into pneumatic actuator and electric actuator, more commonly used actuators are the two, we will choose gas when buying. Actuator.

Then we have to choose the actuator according to the size of the air source. The torque needed to rotate the valve can not be changed, and the service life of the valve is not long if it is too big. Typically, a 30% allowance for torque is OK. Pneumatic actuators can be seen from the text that such actuators are operated by air pressure. Compared with the electric actuator, it can adapt to more environments, and its load force is greater with reasonable structure, thus achieving the goal of high torque output. At the same time, compared with the electric actuator, the action is faster and the response is faster. Of course, electric actuators also have many advantages that pneumatic actuators can't compare with, and the advantages of pneumatic actuators are also what current electric actuators do not have. Both of them have their own disadvantages and advantages. Therefore, under the continuous development of science and technology in the future, the performance-price ratio of the two will be greatly improved.
