Knife-type gate valves, also known as knife gate valves or knife-type slurry valves, were introduced to China from the 1980s. Its application range is very wide, from coal mining in mines and power plants, slag discharge, slag discharge, to urban sewage treatment; from cement and paper mill slurry transportation to food, sanitation, medicine and other professional pipelines. The ultra-thin design of the knife-type gate valve completely solves the ordinary gate valve, the slab gate valve, the ball valve, the globe valve, the regulating valve, the butterfly valve and the like with the advantages of small volume, light weight, small flow resistance, no slag accumulation, easy installation and easy disassemble. The flow resistance is large, occupying space, easy to accumulate slag, and difficult to install and maintain. Therefore, a large number of general-purpose cut-off gates and regulating gates are replaced by knife-type gate valves.
