Metal seal butterfly valve

Metal seal butterfly valve

Hard seal butterfly valve is also called Metal seal butterfly valve, the advantage is that the structure of short, small size, light weight, portable operation. The use of axle structure, butterfly plate using truss structure, high strength, large over-current, small flow resistance, energy saving.

Wafer hard-sealed butterfly valve using sophisticated J-shaped 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 water supply and drainage and municipal building Industrial pipe for regulating the flow and use body contained devascularization 
Features
1, on the clip-on hard-sealing three-eccentric butterfly valve seal structure, with the butterfly valve plate almost no wear and tear, with the more stringent 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, on the clip-on 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 180degree C ) to install, user-friendly
