D943H D943Y three eccentric flange hard sealing electric butterfly valve

Product use:

D43H, D343H, D643H, D943H PN10 ~ PN100 three eccentric flange hard sealing electric butterfly valve adopts precise J-shaped elastic seal ring and three eccentric multi-layer metal hard sealing structure, which is widely used in metallurgy, electric power, petrochemical, water supply and drainage, municipal construction and other industrial pipelines with medium temperature ≤ 400 ℃ to regulate flow and carry off fluid.


Structure diagram:


Product features:

1. The metal hard seal butterfly valve adopts three eccentric seal structure, with almost no wear on the valve seat and butterfly plate, and the tighter the sealing function.
2. The sealing 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 no matter at low or high temperature.
3. The sealing surface of butterfly plate is overlaid with cobalt based cemented carbide, which is wear-resistant and has long service life.
4. Large size butterfly plate adopts quilting frame structure, with high strength, large flow area and small flow resistance.
5. Metal hard sealing butterfly valve has two-way sealing function, which can be installed in any direction without the restriction of medium flow direction and space position.
6. The driving device can be installed in multiple positions (rotated 90 ° or 180 °), which is convenient for users.


Valve model:

Common three eccentric flange hard seal electric butterfly valve models are D943H-6, D943H-10, D943H-16, D943H-25, D943H-40, D943H-64, D943H-100, D943Y-6, D943Y-10, D943Y-16, D943Y-25, D943Y-40, D943Y-64, D943Y-100, etc.
