PZ73H-10C manual knife gate valve, also called knife gate valve, is suitable for pipelines with suspended particles, fiber materials such as pulp, sewage, coal slurry, ash, cement mixtures and other media, relying on the knife-edge gate that can cut fiber materials to cut off these media. Valve body actually does not exist chamber, the gate in the side guide groove lift, and have the bottom lugs tightly pressed on the valve seat, such as the need to achieve a high media sealing, O-shaped sealing seat can be used to achieve bidirectional sealing. The valve has the characteristics of light and flexible operation, small size, smooth channel flow, small flow resistance, light weight, easy to install, easy to disassemble and so on. Knife gate valve with a shear function of the gate can scrape the adhesion on the sealing surface, automatic removal of debris, stainless steel gate can prevent corrosion caused by seal leakage. Widely used in sewage, coal slurry, molasses, mud, air, slag-water mixtures, water supply, papermaking, mining and other industries.
