Electric Knife Type Gate Valve PZ973X

The opening and closing component of the electric knife gate valve is the gate plate, and the direction of movement of the gate plate is perpendicular to the direction of the fluid. The manual knife gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve has two sealing surfaces. The two sealing surfaces of the commonly used mode gate valve form a wedge shape, and the wedge angle varies with the valve parameters, usually 50. The gate of the wedge knife gate valve can be made as a whole, called a rigid gate valve; It can also be made into a gate plate that can produce slight deformation to improve its processability and compensate for the deviation of the sealing surface angle during the processing. This type of gate plate is called an elastic gate plate. Most knife type gate valves use forced sealing, that is, when the valve is closed, the gate plate needs to be forcibly pressed against the valve seat by external force to ensure the sealing surface. This type of valve should generally be installed horizontally in pipelines.
