Manually paste gate points wafer and integral, and the wafer body sealing adopts composite configuration "U" type and "T" type composite structure. One-piece body sealing adopts composite seal "O" type structure, overcomes the original wafer slurry valve adopts "U" type gasket stress after the displacement and deformation, such as medium leak faults. With simple structure, small volume, light weight, small flow resistance, medium is not easy to precipitate in the body, as well as convenient installation, and many other advantages. Used in paper making, petrochemical, mining, water drainage, food and other industries.

The company has all kinds of sizes, pressure, different materials, connections, drive mode of all types of gate valve. Please contact or consult online.
Manual pulp gate valve, because of the use of knife gate, has a good shear effect, suitable for pulp, powder, fiber and other difficult to control the fluid, widely used in paper, petrochemical, mining, drainage, food and other industries. A variety of seat options are available and the valve can be automated with electric or pneumatic actuators depending on field control requirements. Material: cast iron, carbon steel, stainless steel size range :DN50~DN600 larger pressure: 1.0mpa knife gate valve because of the use of knife gate, with good shear effect, suitable for pulp, powder, fiber and other difficult to control the fluid, widely used in paper, petrochemical, mining, drainage, food and other industries. A variety of seat options are available and the valve can be automated with electric or pneumatic actuators depending on field control requirements. Material: cast iron, carbon steel, stainless steel size range :DN50~DN600 pressure: 1.0mpa
