soft sealing butterfly valve

High-performance soft seal butterfly valve, characterized in that: the said seat seal ring consists of a soft T-shaped sealing ring on both sides of a multi-layer stainless steel sheet.

The sealing surface of the valve plate and the valve seat is oblique cone structure, in the valve plate oblique cone surface overlay welding temperature and corrosion resistant alloy material; fixed in the adjustment ring between the pressure plate spring and the pressure plate on the adjustment bolt assembly together with the structure. This structure effectively compensates for the tolerance zone between the sleeve and the valve body and the elastic deformation of the valve stem under medium pressure, solving the sealing problem of the valve in the process of two-way interchangeable medium transmission.
