Electric Knife Gate Valve

The opening and closing part of the knife gate valve is the ram, and the movement direction of the gate is perpendicular to the direction of the fluid. The knife gate valve can only be fully opened and closed, and can not be adjusted and throttled. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valves form wedges and wedge angles that vary with the parameters of the valve, usually 50. The sluice of the wedge type knife gate valve can be made into a whole, called a rigid gate, and a sluice which can produce a trace deformation to improve its craft and make up the angle of the seal face. Deviations produced in the process of work.
