Three eccentric hard seal butterfly valve adopts three eccentric structure, the valve seat and disc plate sealing surface are made of different hardness and stainless steel, with two-way sealing function, the product conforms to the national GB/T13927-92 valve pressure test standard. Therefore, it is widely used in the medium Temperature≤425 ℃ gold, electric power, petrochemical, and water supply and drainage and municipal construction and other industrial pipelines, for regulating the flow and carrying off the fluid use.

Three eccentric hard seal butterfly valve adopts three eccentric sealing structure, the valve seat and the butterfly plate is almost no wear, with the more view the tighter the sealing function, the sealing ring is made of stainless steel, with the double advantages of metal hard seal and elastic sealing, no matter in the case of low temperature and high temperature, have excellent sealing performance, corrosion resistance, long service life and other characteristics.

The sealing surface of the disk plate is made of surfacing cobalt-based hard alloy, the sealing surface is wear-resistant and has a long service life, and the large-size butterfly plate adopts a quilted frame structure, which has high strength, large over-flow area and small flow resistance, and the hard seal butterfly valve has a bidirectional sealing function, and the installation is not subject to the restriction of the flow direction of the medium or the influence of the spatial position, so it can be installed in any direction, and the drive can be installed at multiple positions (rotated by 90° or 180°), which is convenient for users to use. It can be installed in any direction.
