D941H-2.5C electric hard seal butterfly valve Product Overview: D941H-2.5C electric hard seal butterfly valve can I plant the introduction of foreign advanced technology, the use of sophisticated J-shaped flexible ring and three eccentricity metal hard sealing multi-layered structure, electric hard sealing butterfly valve is widely used in medium temperature of ≤ 425 ℃ metallurgy, electric power, petrochemical, as well as to the drainage and municipal construction and other industrial pipe for regulating the flow and set off fluid used. Electric hard seal butterfly valve with three eccentric structure, seat and disc sealing surface are made of stainless steel with different hardness and has good corrosion resistance, long life, has a two-way electric hard seal butterfly valve sealing function, electric hard seal butterfly valve in line National GB/T13927-92 valve pressure test standards. D941H-2.5C Electric Butterfly Valve Features: 1, D941H-2.5C electric three eccentric hard sealing butterfly valve seal structure, seat and disc almost no wear, with more and more tightly sealing function concept. 2, seals made of stainless steel production, with a metal seal and elastic sealing double advantage, both in the case of low and high temperatures, both with excellent sealing performance, corrosion resistance, long life and other characteristics. 3, dish plate sealing surface using cobalt-based alloy welding, sealing surface wear resistance, long service life. 4, large-sized butterfly plate with lattice structure, high strength, large flow area, small flow resistance. 5, the electric hard seal butterfly valve with two-way sealing function, the impact of limiting the flow of the installation from the media, but also from spatial location, can be installed in any direction. 6, the drive means may be multi-bit (90 ° rotation or 180 °) to install, easy to use.
