  • Features of Triple Eccentric Butterfly Valve

    The Triple Eccentric Metal Hard Seal Butterfly Valve uses an elastic stainless steel seal ring installed on the valve body to achieve true zero leakage. It is generally used in special occasions such as high temperature and medium with particles.

  • 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.
