This butterfly valve connection for butt welding, is a long life, energy-efficient butterfly valve products. Widely used in electric power, petroleum, chemical industry, metallurgy, municipal construction and other industrial piping for truncated or adjust medium flux.

1, the structure size is short, small volume, light weight, convenient operation;

2, with the shaft structure, butterfly plate the intensity is high, the flow area is large, small flow resistance, save energy;

3, butterfly plate sealing surface using cobalt-based carbide surfacing, sealing surface wear resistance, long service life;

4, use three eccentric sealing structure, the seat and disc almost no wear and tear, have the close tight sealing function.
