  • Gate valve movement mode

    When the gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, only rely on the medium pressure to press the sealing surface of the gate plate to the valve seat on the other side to ensure the sealing of the sealing surface, which is self-sealing. Most of the gate valve is forced seal, that is to say, when the valve is closed, the gate should be pressed to the valve seat by external force, so as to ensure the sealing surface sealing.

  • How Gate Valve Works？
