One, worm gear multi - level hard seal butterfly valve - overview
D373H spiral gear multi-level hard seal butterfly valve adopts precision J-shaped elastic sealing ring and three eccentric multi-level metal hard seal structure, is widely used in the medium temperature ≤425℃ gold treatment, electric power, petrochemical, water supply and drainage and municipal construction and other industrial pipelines, used to regulate the flow and load and stop flow body. The valve adopts three eccentric structure, the valve seat and plate sealing surface are made of different hardness and stainless steel, with good corrosion resistance and long service life
Two, worm gear multi - level hard seal butterfly valve - characteristics
1, D373H worm gear multi-level hard sealing butterfly valve adopts three eccentric sealing structure, valve seat and butterfly plate almost no wear, with the more tight sealing function.
2, the sealing ring is made of stainless steel, with the double advantages of metal hard seal and elastic seal, no matter in the case of low temperature and high temperature, it has excellent sealing performance, corrosion resistance, long service life and other characteristics.
3. The sealing surface of the plate is hardfaced with cobalt-based carbide, and the sealing surface is wear-resistant and has long service life.
4, the large size of the butterfly plate adopts quilting structure, high strength, large flow area, small flow resistance.
5, the valve has a two-way sealing function, installation is not limited by the flow of the medium, also not affected by the space position, can be installed in any direction.
6, the driving device can be multi station (rotation 90° or 180°) installation, convenient for users to use.
