Dongyu Environmental Protection Manual Knife Gate Valve Made of Cast Steel Material, with Manual Drive and Bidirectional Flow Customizable

The opening and closing component of the knife type gate valve is the gate, and the movement direction of the gate is perpendicular to the direction of the fluid. Manual knife type gate valves can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate has two sealing surfaces, and the most commonly used mode is that the two sealing surfaces of the gate valve form a wedge shape. The wedge angle varies with the valve parameters, usually 50. The gate of the wedge knife type gate valve can be made into a whole, called a rigid gate; It can be made into a gate that can produce slight deformation to improve its processability and compensate for the deviation in the sealing surface angle during the processing. When the elastic gate knife type gate valve is closed, the sealing surface can rely on medium pressure to seal, that is, the sealing surface of the gate can be pressed towards the other side of the valve seat to ensure the sealing surface. When the valve is closed, external force must be used to forcefully press the gate towards the valve seat to ensure the sealing surface.
