D373H/Y type sandwich hard seal butterfly valve，Sandwich hard seal butterfly valve，Hard seal butterfly valve

Product Overview

D373H, D373Y type sandwich-type 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.

Product Features

1, sandwich type hard seal 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 butterfly 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 sandwich type hard seal butterfly valve has a two-way sealing function, the installation is not limited by the flow of the medium, nor by the influence of the spatial 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.
