Structural features
1. The hard seal butterfly valve with three eccentric hard seal 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 butterfly plate sealing surface using welding cobalt-based hard alloy, sealing surface wear-resistant, long service life.
4. Large-format butterfly plate frame structure, high strength, large flow area, small flow resistance.
5. According to user needs, the valve supply network of hard-sealing butterfly valve can be designed to have a two-way sealing function, the installation of media flow from the restrictions, but also the impact of space location, can be installed in any direction.
6. The drive can be multi-station (rotated 90 ° or 180 °) installation, user-friendly.
