hard sealing worm gear butterfly valve

Hard Seal Butterfly Valve
Poduct use
Hard seal butterfly valve using flexible ring and three eccentricity metal hard sealing multi-layered structure, are widely used in medium temperature of < 425 Degree C metallurgy, electric power, petrochemical, as well as to the drainage and municipal construction and other industrial pipe for regulation of body volume and stop the use of set
Features
1, hard-sealing three-eccentric butterfly valve seal structure, butterfly valve seats and almost no wear plate with a more compact view of the sealing function of the more
2, selection of stainless steel ring with a metal hard sealing and sealing of the double advantage of flexibility in terms of low temperature and high temperature cases, both with excellent sealing performance, with a corrosion-resistant, long service life, etc.
3, butterfly plate sealing surface using cobalt-based hardfacing alloy, wear-resistant sealing surface, long service life
4, the use of large-sized butterflies hang board structure, high strength, cross-flow area, flow resistance in small
5, hard-seal butterfly valve with two-way sealing function, the flow of the installation media without restrictions, but also from the effects of spatial location can be installed in any direction
6, can drive multi-bit (rotation 90 Degree C or 180 Degree C) to install, user-friendly
