Forged Steel Flange Gate Valve

Forged steel flange gate valve belongs to a kind of forging gate valve. The opening and closing parts of gate valve are gate plates. The direction of motion of gate plates is perpendicular to the direction of fluid. According to the sealing surface configuration can be divided into wedge gate valve and parallel gate valve, most of the gate valve is forced to seal, that is, when the valve is closed, to rely on external force to force the gate to the seat, in order to ensure the sealing surface.
