Product Name: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


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

2.Selection of stainless steel ring with a metal seal and sealing the dual advantages of flexibility, both in the case of low temperature and high temperature, all have excellent sealing properties, resistant to corrosion, long service life and so on.

3. Dish plate sealing surface using cobalt-based alloy welding, sealing surface wear resistance and long service life.

4.Large-sized butterfly plate with lattice structure, high strength, over-current area, flow resistance small.

5.This valve has bi-directional sealing capabilities, installation, media flow is not restricted, but also from the impact of spatial location can be installed in any direction.

6.Drives can be multi-bit (rotated 90 ° or 180 °) to install, easy to use
