In the industry, we often hear Triple Eccentric Butterfly Valve  because of its good characteristics, tri-eccentric butterfly valve is widely used. Do you know what is a multi-level tri-eccentric metal seal pair butterfly valve? What are the characteristics of multi-level three-eccentric butterfly valve? Let's follow Ruito Xiaobian to get to know it.
Multi-level Three-eccentricity metal hard seals with two-way pressure adopt precise J-shaped elastic ring and Three-eccentricity multi-level metal hard seals. They are widely used in gold treatment, power, petrochemical industry, water supply and drainage, municipal construction and other industrial pipelines whose medium temperature is less than 425 degrees Celsius. The valve is made of different hardness and stainless steel. It has good corrosion resistance and long service life. The valve has two-way sealing function. The product meets the national GB/T13927-92 valve pressure test standard.

Multi-level Three-eccentricity metal hard seal two-way pressure butterfly valve product characteristics:

1. The valve adopts a three-eccentric sealing structure. There is almost no wear and tear between the seat and butterfly plate. It has the sealing function of tighter and tighter.
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, no matter at low temperature and high temperature.
3. Surfacing cobalt-based cemented carbide is used on the sealing surface of disc plate. The sealing surface is wear-resistant and has a long service life.
4. Large size butterfly plate adopts quill structure, which has high strength, large overflow area and small flow resistance.
5. The valve has two-way sealing function. It can be installed in any direction without restriction of medium flow direction or influence of space position.
6. The driving device can be installed at multiple stations (rotating 90 or 180 degrees) for user's convenience.
The above is the product characteristics of multi-level three-eccentric butterfly valve.
