Knife-shaped gate valve-also known as knife-shaped gate valve, knife-shaped slurry valve, entered my country in the XNUMXs.In less than two decades, its scope of use has expanded from ordinary fields to a wider range of industries.Coal preparation, gangue discharge and slag discharge from mines and power plants.It has developed into urban sewage treatment, and has developed from general industrial pipelines to professional pipeline systems such as food, sanitation, and medicine.The ultra-thin knife gate valve completely solves the large flow resistance and weight of flat gate valves, ball valves, globe valves, regulating valves, butterfly valves and other valves with its advantages of small size, small flow resistance, light weight, easy installation, and easy disassembly. Difficult problems such as large size, difficult installation, and large area.
After the appearance of the knife gate valve, a large number of general shut-off valves and regulating valves have been replaced.To date, the world's largest consumption of knife gate valves is the United States and Japan.
