  • Features of Soft Seal Butterfly Valve

    With the increase of the reverse medium pressure, when the unit positive pressure between the soft-sealed butterfly valve plate and the soft-sealed butterfly valve seat is less than the medium pressure, the deformation stored in the spring of the adjusting ring after loading can compensate the soft-sealed butterfly valve plate and the soft-sealed butterfly valve seat. The tight pressure on the sealing surface of the sealing butterfly valve seat plays an automatic compensation role.

  • The Difference Between Hard Seal and Soft Seal of Butterfly Valve

    1.The hard seal of the butterfly valve means that both sides of the seal pair are made of metal materials or harder materials. The hard seal has high temperature resistance, wear resistance and good mechanical properties.

  • 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 to choose electric valve and pneumatic valve
