Stainless Steel Gate Valve

The opening and closing parts of gate valves are gate plates, and the movement direction of the gate plates is perpendicular to the direction of the fluid. The gate valves can only be fully opened and closed, and can not be adjusted or 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 and 2 52'when the medium is not high. The sluice gate of a wedge valve can be made into a whole, called a rigid gate, 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, which is called an elastic gate.
