The varieties and quantities of butterfly valves are still expanding, and they are developing towards high temperature, high pressure, large diameter, high sealing, long service life, excellent regulating characteristics and multi-functionality of valves. The reliability and other performance indicators of Lever-operated wafer concentric butterfly valve are all equal. It has reached a relatively high level and has partially replaced stop valves, gate valves and ball valves. With the advancement of butterfly valve technology, in the foreseeable short term, butterfly valves will become the dominant type of valve, especially in the fields of large and medium-sized diameters and medium and low pressure. To meet the requirements of industrial applications such as high and low temperatures, strong erosion, and long service life.
