With the continuous development of domestic industry, the demand for insulated pneumatic ball valves used on pipelines is also increasing, and the requirements for insulated pneumatic ball valves are also increasing. When users select insulated pneumatic ball valves, they pay special attention to whether the valves have good sealing performance to prevent medium leakage. Due to the good reliability of imported thermal insulation pneumatic ball valve, users often use imported thermal insulation pneumatic ball valve for important parts. However, the imported thermal insulation pneumatic ball valve is expensive, with a long delivery period and inconvenient after-sales service, which seriously affects the operation of the entire pipeline. In order to reduce pipeline costs and realize the localization of thermal insulation pneumatic ball valve, domestic manufacturers also constantly strive to improve the quality and sealing reliability of domestic thermal insulation pneumatic ball valve, and strive to replace the imported thermal insulation pneumatic ball valve.

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.
