Knife Gate Valve

Knife gate valve, also known as knife slurry gate valve, Its application range is very wide, from coal preparation, gangue and slag discharge in mines and power plants to urban sewage treatment; from slurry transportation in cement and paper mills to professional pipelines such as food, health and medicine.

The ultra-thin knife gate valve has the advantages of small size, light weight, small flow resistance, no slag accumulation, easy installation and easy disassembly, which completely solves the difficult problems of ordinary gate valves, flat gate valves, ball valves, stop valves, regulating valves, butterfly valves, etc., such as large flow resistance, space occupation, easy slag accumulation, and difficult installation and maintenance.

Therefore, a large number of general cut-off valves and regulating valves have been replaced by knife gate valves.
