Dark stem resilient seat seal gate valve using the valve plate encapsulated rubber to produce deformation compensation effect to achieve good sealing effect, overcoming the general sealing of the gate valve bad, water leakage and rust phenomenon, more effective to save installation space, soft seal gate valve bottom of the whole basin straight-through flow design, equivalent to straight pipeline, no stagnant concave cavity structure, flow resistance is small, to ensure that the fluid flows freely. It is not easy to deposit debris, and will not cause secondary pollution to the medium.
