Concealed stem wafer type knife gate valve is a new type of gate valve. It is small in size, light in weight and light in material saving. It is an ideal product for sewage, coal slurry, mud, air, slag-water mixture, water supply, papermaking, mining and other industries. Knife gate valves use metal-to-metal hard seals, or metal-to-rubber soft seals. In the process of opening and closing, the gate and sealing surface adopt a special design, which has less friction and is durable.
