Features of pneumatic butterfly valve: the circular butterfly plate rolling with the valve is used for opening and closing, and the pneumatic valve that has completed the start action is mainly used as the shut-off valve. According to the structural characteristics of the pneumatic butterfly valve, it can also be planned to have the function of dispatching or section valve and dispatching. Now, the use of butterfly valves in low-pressure large and medium caliber pipelines is increasing. In fact, many equipment have pneumatic butterfly valves, especially on the pipeline, but we must not underestimate it. However, many people have heard of pneumatic butterfly valve for the first time, and they do not understand its advantages and disadvantages. But don't worry about the advantages and disadvantages of pneumatic butterfly valves.

Due to certain differences in the requirements of various consumer enterprises for the design, manufacturing and inspection of non-metallic compensators, there is no unified specification that can be followed. Some terms are mainly reserved through the technical agreement between the supplier and the demander. In view of this situation,
According to the relevant specifications, the Technical Committee for Standardization of Instrument Components organizes relevant units in the non-metallic compensator manufacturing industry and relevant national testing institutions to formulate the industrial specifications for machinery industry and the classification specifications for non-metallic compensators, so that the specifications can better guide the design and manufacturing of non-metallic compensators for pipes and equipment, Inspection, etc., change the current difficult state without rules to improve the design and manufacturing of non-metallic compensators for pipes and equipment
