Metal Seated Flange Knife Gate Valve

The KOSEN Metal Seated Flange Knife Gate Valves, its opening and closing is the gate, the direction of the motion of the gate is perpendicular to the direction of the fluid, and the medium is cut off by cutting the blade of the fiber material. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valve form the wedge and wedge angle with the valve parameters, usually 5 degrees, and the wedge-shaped knife type gate valves. The sluice can be made into a whole, called a rigid sluice board, or a sluice which can produce a small amount of deformation to improve its craft and make up for the deviation produced by the angle of the sealing surface in the process of processing. This gate is called an elastic gate. In fact, the valve body does not exist, the gate is lifted in the side guide slot, and the lug at the bottom is pressed on the seat. If a high medium seal is needed, a O - shaped seal can be used to achieve a two-way seal. The knife gate valve has smaller installation space, low working pressure, less accumulation of debris and low price.
