Wafer Butterfly Valve uses sophisticated J-shaped elastic ring and three eccentric multi-level metal seal structure, which is widely used in medium temperature ≤425 ℃ of metallurgy, electric power, petrochemical, as well as drainage and municipal construction and other industries pipelines, for regulating the flow and load off fluid use.
Features：
1、Wafer Butterfly Valve with three eccentric seal structure, seat and disc almost no wear, with more and more tightly sealed off function；
2、Ring made of stainless steel production, with a metal seal and elastic sealing of the dual advantages；
3、Wafer butterfly valve has bi-directional sealing function, affecting the flow of the installation from the medium restrictions, and are not subject to spatial location can be installed in any direction；
4、Drive device can be multi-position (rotated 90 ° or 180 °) to install, easy to use；
