The pneumatic high pressure ball valve is mainly used to control the opening and closing of the valve through a rotating valve core. It is a relatively small valve with simple structure, convenient use, and simple maintenance. At the same time, it has good sealing performance and is not easy to be eroded by media when it is closed. It has a very wide range of applications in various industries. When it is used, the speed of cutting off the medium flow is very fast, and it can quickly change the direction of the medium flow and the size of the flow. It is a new type of valve that has emerged in recent years.

　　Its scope of application has now been widely spread in all industries of industrial production, including chemical, paper and other industries, and also has great use in the aviation industry. The main features are as follows: the medium passing through the valve is subject to small resistance and can pass smoothly. Good sealing performance. At present, one of the most used sealing materials is plastic, which is a soft material with very good sealing performance and is not easy to be eroded by medium solution.

　　The speed of the switch is fast. It only needs to rotate the valve core 90 degrees from the closed state to the fully open state, which is very suitable for remote control. Because the structure is relatively simple, it is relatively simple in both installation and maintenance. You can judge the fault in a relatively simple way. The scope of application is relatively wide, from a few millimeters of pipe to a few meters of pipe can be connected, whether vacuum or high-pressure can be used. Because gas is used as the power, the safety can be guaranteed, and if there is gas leakage, the gas can be discharged directly without causing pollution to the environment.
