The  knife gate valve is a specific design of a valve that uses a knife edge that can enter the flow stream and, if necessary, use the edge of the gate to separate any materials that might prevent the valve from sealing completely.The knife gate valve has solved the problems of ordinary gate valves such as heavy weight, large flow resistance, large area and difficulty in installation. It can be eliminated by cutting off the valve. It can work under the working pressure of 1.0Mpa-2.5Mpa and the  temperature of -29-550℃. The valve plate of the knife gate valve has a shearing function, which can scrape off the adhesive inside the seal and automatically remove debris. The stainless steel gate valve can prevent seal leakage caused by corrosion.

Knife gate valves are suitable for coal preparation, slag discharge, urban sewage treatment, food, paper making, medicine, petroleum, chemical and other oil, water, steam pipelines in mining plants, or for cutting off cement slurry, gold ore powder, ore in pipelines. Slag furnace, coal slime, paper pulp, wood pulp, fiber, chemicals, chemical sewage treatment, sedimentation tank, fork, silo outlet, fruit, grain, slaughterhouse wastewater and other media.
