The pressure self-sealing forged steel gate valve is a wedge-type gate with two ring airtight cover, wedge into the wedge body cavity of the two ring type sealing surface, and realize the sealing function.
On either side of the valve is closed, on both sides of the gate and seat sealing surface contact through increasing gate insertion force, make the damper produces elastic or plastic deformation, flush with the valve seat sealing surface contact seal completely, stop the medium flow.
