Manual knife gate valve is a new structure of the valve, divided into soft seal and hard seal, soft seal with movable seat and replaceable rubber ring composition, can achieve good sealing requirements. Branch knife gate valve is suitable for horizontal installation, also tilt installation, suitable for syrup, pulp, sewage, coal slurry, ash, dust, slag and water mixtures and other media pipeline, can be used as a medium to cut off and throttling, is widely used in papermaking, industrial and mining, sewage, chemical industry, food field.

Manual knife gate valve ultra-thin design knife gate valve with its small size, light weight, small obstruction of flow, do not accumulate slag, easy to install, easy to dismantle the advantages of a complete solution to the common gate valves, flat gate valves, ball valves, globe valves, regulating valves, butterfly valves, and other valves, such as the obstruction of large, space-occupying, easy to accumulate slag, not easy to install and repair and other difficult problems. Therefore, a large number of general-purpose cut-off type valves and regulating valves are replaced by knife gate valves.

Manual knife gate valve from mining power plant coal, gangue, slag discharge. Developed to the city's sewage treatment, from the general industrial pipeline development to the food, health, and other pipeline systems. Manual knife gate valve with its small size, small flow resistance, light weight, easy to install, easy to dismantle and other advantages to solve the common gate valve, plate gate valve, ball valve, globe valve, regulating valve, butterfly valve and other types of valves with large flow resistance, heavy weight, difficult to install, large floor space and other difficult problems. Knife gate valve appeared, a large number of general-purpose cut-off class valves and regulating valves have been replaced.
