The main function of pneumatic high-pressure ball valve is to change the flow direction of medium in the pipeline. At the same time, the ball valve also has the function of regulating flow. Due to the high temperature and high pressure resistance of the ball valve, the ball valve has become one of the leading types in the valve industry. In fact, the function principle of the ball valve is very simple. The ball valve exerts a certain force on the valve stem through the drive device, and transmits this force to the ball, thus controlling the ball to rotate 90 degrees, Make the passage of the ball vertical or parallel to the centerline of the passage of the valve body itself, so that the ball valve can complete the whole process of closing or opening the valve completely. 　　

Throughout the global market of pneumatic butterfly valves, there is still an upward trend. For example, in China, butterfly valves are increasingly used in pipelines in some key construction projects, especially in sewage treatment, which also forms strong market competition. However, the domestic valve industry is still dominated by labor-intensive enterprises, which has led many foreign companies to gradually transfer their productivity to China.
