Products Name:D73H Handle Pair Butterfly Valve

D73H handle pair butterfly valve adopts precise J-shaped elastic sealing ring and three eccentric multi-layer metal hard sealing structure. It is widely used in metallurgy, electric power, petrochemical industry, industrial pipelines such as water supply and drainage and municipal construction with medium temperature ≤ 425 °C. Above, used to regulate flow and load fluid. The valve adopts three eccentric structure, the valve seat and the disc sealing surface are made of different hardness and stainless steel, which has good corrosion resistance and long service life.

Detailed description

D73H handle pair butterfly valve features:

1. Small volume, light weight, simple structure, small fluid resistance and operating torque, convenient operation and labor-saving;

2, three-dimensional eccentric structure, so that the butterfly plate is tighter and tighter, its sealing performance is reliable, reaching zero leakage;

3, open and close quickly, easy to operate, just rotate 90 degrees;

4, high pressure, corrosion resistance, wear resistance, long service life.
