It has developed to urban sewage treatment, from general industrial pipelines to food, sanitation, and other pipeline systems. The ultra-thin knife gate valve has the advantages of small size, small flow resistance, light weight, easy installation and easy disassembly, etc. to solve the large flow resistance of ordinary gate valves, flat gate valves, ball valves, globe valves, regulating valves, butterfly valves and other valves. Difficult problems such as heavy weight, difficult installation, and large floor space. After the appearance of the knife gate valve, a large number of general-purpose shut-off valves and regulating valves have been replaced by them.
