Butterfly Valve(Flanged Hard Seal)

Product Description 
I. Product Overview

  I plant the introduction of advanced foreign technology can be based on the use of sophisticated J-shaped flexible ring and three eccentricity metal hard sealing multi-layered structure,Are 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 the use of drying body.The three-eccentric valve structure, valve seat and disc sealing surface plate are stainless steel with different hardness and production, has good corrosion resistance, long service life, the valve seal has a two-way functions, products, in line with national GB/T13927-92 valve pressure test standard.

Second, the characteristics of

1, the valve sealing three-eccentric structure, the valve seat and the butterfly board almost no wear and tear, with more tightening of the sealing concept features.

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 life and so on.

3, disc 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, large over-current, small flow resistance.

5, the valve seal has a two-way function, from the installation media restrictions on the flow, but also from the effects of spatial location can be installed in any direction.

6, can drive multi-bit (rotation 90 ° or 180 °) to install, user-friendly.
