First, the flange multi-layer metal seal butterfly valve Product Overview:

The valve uses sophisticated J-shaped elastic ring seal and three eccentric multi-level metal hard seal structure, is widely used in metallurgy, power, petrochemicals, temperature, temperature, etc., and industrial pipelines such as water supply and drainage and municipal construction Regulate flow and interrupt fluid usage. The valve uses three eccentric structure, the valve seat and the disc sealing surface are made of different hardness and stainless steel, with good corrosion resistance, long service life, the product complies with national GB / T13927-92 valve pressure test standards.
 

Second, the flange multi-layer metal seal butterfly valve Features:

1, the valve adopts three eccentric sealing structure, the valve seat and disc almost no wear, with the more the more tight sealing function.

2, the ring made of stainless steel, with the advantages of both metal seal and flexible seal, both in the case of low temperature and high temperature, have excellent sealing performance, with corrosion resistance, long service life and so on.

3, the sealing surface of the plate is cladded with cobalt-based cemented carbide, the sealing surface is resistant to wear and has a long service life.

4, Large-format butterfly plate frame structure, high strength, large flow area, small flow resistance.

5, the valve has a two-way sealing function, the installation is not subject to restrictions on the flow of media, but also the location of space, can be installed in any direction.

6, the drive can be multi-station (rotated 90 ° or 180 °) installation, user-friendly.
