Product Name:Electric Wafer Hard Seal Butterfly Valve
Product Classification:Butterfly valves
Product Introduction: The butterfly valve, based on introducing the foreign advanced technology, using sophisticated J-shaped flexible seal ring and three eccentric multi-level metal seal structure, and is widely used in the petroleum, chemical industry, metallurgy, water, electricity and many other areas which media temperature ≤425℃.It is used to achieve piping system as an on-off and flow control components. The valve, using three-eccentric structure, valve seat and disc sealing surface are made of stainless steel with different hardness. And have good corrosion resistance and long life. It’s has the bi-directional sealing function and be in line with national GB/T 13927-92 valve press test standard.
Description Parameters Size Chart Application
Feature
1.        Three-eccentric seal structure, seat and disc almost no wear, with the more closed more tightly sealing function.
 
2.        Seal ring made of stainless steel, with dual benefits of metal seal and flexibility. No matter in the case of low temperature or high. Both with excellent sealing properties, resistant to corrosion, and long service life.
 
3.        Disc sealing surface using cobalt-based alloy welding, sealing surface wear resistance and long service life
 
4.        Large size disc using lattice structure, high strength, flow area large, small flow resistance.
 
5.        The valve has a two-way sealing function, the installation media from the flow restriction are not subject to the impact of spatial location. Can be installed in any direction.
 
6.        Drive can be multi-position(rotated 90°or 180°)to install. Easy to use.
