Product Introduction
The opening and closing part of the rubber seal gate valve is the gate plate. The movement direction of the gate plate is perpendicular to the fluid direction. The gate valve can only be fully opened and closed, and cannot be adjusted or throttled.It achieves a good sealing effect by utilizing the deformation compensation effect generated by the encapsulation of the valve plate, overcomes the phenomena of poor sealing, water leakage and rust of common gate valves, and more effectively saves installation space. The bottom of the rubber seal gate valve adopts a straight-through flow passage design of the whole basin, which is equivalent to a straight pipe, has no stagnant flow cavity structure, has small flow resistance, ensures smooth flow, is not easy to deposit sundries, and does not cause secondary pollution to the medium.
