Three eccentric butterfly valves for extraction and auxiliary steam

1. The metal hard seal butterfly valve adopts three eccentric sealing structure, and the valve seat and butterfly plate have almost no wear, and the sealing function of the closer the valve is closed;
2. The seal ring is made of stainless steel, which has the double advantages of metal hard seal and elastic seal. It has excellent sealing performance, corrosion resistance and long service life under low and high temperature conditions;
3. The sealing surface of butterfly plate adopts hardfacing cobalt based cemented carbide, which is wear-resistant and has long service life;
4. Large size butterfly plate adopts truss structure with high strength, large flow area and small flow resistance;
5. The valve has two-way sealing function. It is not limited by the medium flow direction and the space position. It can be installed in any direction;
