Excellent sealing performance, corrosion resistance, long service life and other characteristics. The sealing surface of the disk plate is made of surfacing welded diamond base hard alloy, the sealing surface is wear-resistant and has a long service life. Large size butterfly plate adopts rack structure, high strength, large overflow area, small flow resistance. Butterfly valve with two-way sealing cast iron, installation is not subject to the restrictions of the media flow direction, but also not subject to the influence of the location of the space, can be installed in any direction. The driving device can be installed in multiple positions (rotating 90" or 180"), which is convenient for users to use.
