Product Description


The opening and closing parts of the Flange Knife Gate Valve are the gate, and the movement direction of the gate is perpendicular to the fluid direction. The knife gate valve can only be fully opened and closed, and cannot be adjusted and throttled. The ram has two sealing surfaces, usually 50. The ram of wedge knife Gate Valve can be made into a whole, which is called rigid ram; It can also be made into a ram that can produce slight deformation to improve its processability and compensate for the deviation of sealing surface angle during processing. This ram is called elastic ram. When the knife gate valve is closed, the sealing surface can be sealed only by the medium pressure. Most knife gate valves adopt forced sealing, that is, when the valve is closed, the gate plate shall be forced to the valve seat by external force to ensure the tightness of the sealing surface.

The application range of Flange Knife Gate Valve is:
1. Mining, coal washing, iron and steel industry -- used for coal washing pipeline, slag slurry pipeline, ash discharge pipeline, etc;
2. Purification device -- used for waste water, mud, dirt and clarified water with suspended solids;
3. Papermaking industry -- used for any concentration of pulp and material water mixture;
4. Ash removal in power station -- for ash slurry
