Second, pay more attention to the scientific development of materials, and apply the latest technology and process methods to valves. With the continuous development and progress of the current technical level, various unsafe factors in the industry constantly challenge the new technology of the valve, and also force the valve production industry to constantly improve the process and technology, to produce products with higher safety, stronger functionality, more reliable, and longer service life. 　　

In the end, the pneumatic butterfly valve is mainly divided into automatic control type and manual operation type according to the area used. But generally speaking, valves like this are often used in the control of solid materials. When solid material control is used, it is generally installed at the bottom of various solid material tanks. Of course, there are usually corresponding particles in this solid material. When the pneumatic butterfly valve is opened, these particles will cause certain friction on the valve seal ring and other places. Therefore, when selecting pneumatic butterfly valves, it is necessary to select the products that are most suitable for the construction area, which is the best choice, because this can prevent the materials from damaging the sealing ring of the butterfly valve.
