The pneumatic butterfly valve can select the sealing ring and parts of different raw materials according to the customer's requirements to adapt to different media and working conditions, so as to maximize the application effect of the pneumatic butterfly valve. The actuator of pneumatic butterfly valve can be divided into single effect and double effect modes. The single effect actuator has the function of tension spring reset, which can be closed or opened actively when the air source is lost, and the safety factor is higher! For the double effect pneumatic actuator, when the air source is lost, the pneumatic actuator loses power, and the valve position will remain at the position where the air is lost.

When using the pneumatic control valve, we must pay attention to the model problem. If we can choose the correct model, the most basic work can be completed. If we choose the wrong pneumatic control valve, many problems may occur, such as uncontrollable, or can not be used with other accessories, and even continuous failures, and even increase the maintenance cost.
