Product Description:

Electric flange butterfly valve with three eccentric structure, seat and disc plate sealing surface are made of different hardness and stainless steel, with good corrosion resistance, long service life. Electric flange butterfly valve with precision J-shaped elastic ring and three eccentric Multi-level metal hard seal structure, is widely used in the medium temperature ≤ 425 ℃ governance gold, electricity, petrochemical, and water supply and drainage and municipal construction and other industrial pipelines, for regulating the flow and the use of fluid.

Features:

1. The valve uses three eccentric sealing structure, seat and butterfly plate almost no wear, with the more the more tight the tight seal function.

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

3. Disc plate sealing surface using cobalt-based carbide, sealing surface wear resistance, long service life. Large size butterfly board with a hanging structure, high strength, over flow area, flow resistance is small.

4. The valve has a two-way sealing function, the installation is not subject to the flow of media restrictions, nor the impact of space, can be installed in any direction. The drive can be installed in multiple stations (90 ° or 180 °) for easy user use.
