Which is better, Shanghai electric wafer type soft seal butterfly valve or pneumatic butterfly valve? 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.
、 The electric explosion-proof wafer butterfly valve has good corrosion resistance and long service life. This method has a two-way sealing function. The product complies with the national GB/T13927-92 valve pressure test standard, and is suitable for water supply and drainage of food, medicine, chemical industry, petroleum, power, light textile, paper making, etc
