Wafer Type Knife Gate Valve

Wafer Knife Gate Valve has a good shearing effect because of the Knife Gate, which is most suitable for slurry, powder, fiber, etc
Manual wafer type Gate Valve
Wafer Knife Gate Valve is widely used in papermaking, petrochemical, mining, drainage, food and other industries. A variety of valve seats can be selected, and electric or pneumatic actuators can be equipped according to the demand of on-site control~DN600 maximum pressure: 1.0MPa to realize automatic operation of valves. Material: cast iron, carbon steel, stainless steel Size range: DN50 ～ DN600 Maximum pressure: 1.0MPa knife gate valve has good shearing effect because of the knife gate, which is most suitable for slurry, powder, fiber and other uncontrollable fluids, and is widely used in papermaking, petrochemical, mining, drainage, food and other industries. A variety of valve seats can be selected, and electric or pneumatic actuators can be equipped according to the on-site control requirements to realize the automatic operation of the valve. Material: cast iron, carbon steel, stainless steel
Precautions and characteristics of Wafer Knife Gate Valve : the opening and closing parts of knife gate valve are gate plates, and the movement direction of the gate plate is perpendicular to the fluid direction. The knife gate valve can only be fully opened and closed, and cannot be adjusted and throttled. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valve form wedges, and the wedge angle varies with the valve parameters, usually 50. The gate of wedge knife gate valve can be made into a whole, which is called rigid gate; It can also be made into a ram that can produce slight deformation to improve its processability and make up for the deviation of the angle of the sealing surface during processing. This kind of ram is called elastic ram. When the knife gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the ram is pressed to the valve seat on the other side by the medium pressure to ensure the sealing of the sealing surface, This is self sealing. Most knife gate valves of this type should be installed horizontally in the pipeline.

Forced sealing is adopted, that is, when the valve is closed, the gate shall be forced to the valve seat by external force to ensure the tightness of the sealing surface.
