• The double eccentric structure reduces friction of the sealing ring, providing the valve a long service life.
• Replacing materials of the disc sealing ring, "O" ring, disc and shaft, the valve can be used for various medium and temperature.
• Flange connection is in accordance with GB4216.1-4216.4-84 "Grey Cast Iron Pipe Flanges and Gaskets" and PN1.0MPa, PN1.6MPa flange-connection standard given in BS4504, ISO2084, DIN501

The rolling and pressing type sealing of the traditional butterfly valve haas been changed. It avoids the tearing foding and wearing when operating. Ours products finded favour in domestic and oversea customers and have a vast vistas of the market. That is very popular among the clients in foreign states.
