product description: 

Electric flange type eccentric butterfly valve

The electric flange type eccentric butterfly valve adopts precision U-shaped elastic sealing ring and three eccentric multi-layer metal hard sealing structure, and is widely used in metallurgy, electric power, petroleum, chemical, food, beverage, medicine, etc. with medium temperature ≤ 425 °C. Pure pipelines and industrial environmental protection, water treatment, high-rise buildings, as well as industrial pipelines such as water supply and drainage and municipal construction, for regulating flow and load fluid use.

Electric flange type eccentric butterfly valve features

1. The hard-sealed butterfly valve adopts a three-eccentric sealing structure, and the valve seat and the butterfly plate have almost no wear, and have a tighter and tighter sealing function;

2. The sealing ring is made of stainless steel. It has the double advantages of hard metal seal and elastic seal. It has excellent sealing performance under low temperature and high temperature, and has corrosion resistance and long service life.

3. The sealing surface of the butterfly plate is made of surfacing cobalt-based hard alloy, the sealing surface is wear-resistant and has a long service life;

4. Large-size butterfly plate adopts truss structure, high strength, large flow area and small flow resistance;

5. The hard sealing butterfly valve has a two-way sealing function. It is not restricted by the flow direction of the medium during installation, and is not affected by the spatial position, and can be installed in any direction;

6. The drive unit can be installed in multiple stations (rotated 90° or 180°) for user convenience.
