product description

Product overview

D973H electric hard-seal butterfly valve and electric hard-seal butterfly rice adopt precise j-shaped elastic sealing ring and three-eccentric multi-layer metal hard sealing structure, which are widely used for regulating flow rate and carrying cut-off body in industrial pipelines with medium temperature ≤425℃, such as gold treatment, electric power, petrochemical industry, water supply and drainage, municipal construction and so on. The valve adopts three eccentric structure, the valve seat and disc sealing surface are made of different hardness and stainless steel, with good corrosion resistance, long service life, the valve has a two-way sealing function, the product conforms to the national GB/ t13927-92 valve pressure test standard.

Product features

1, the valve USES three eccentric sealing structure, seat and disc wear.

2, the seal ring is made of stainless steel, with metal hard seal and elastic seal double advantages, no matter in the case of low temperature and high temperature, have excellent sealing performance, corrosion resistance, long service life and other characteristics.

3, plate sealing surface using surfacing welding cobalt base hard alloy, sealing surface wear resistance, long service life.

4, large size butterfly board adopts quilted 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 media, also not affected by the space position, can be installed in any direction.

6. The driving device can be installed at multiple stations (rotating 90° or 180°), which is convenient for users to use.
