Product Name:Welding 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)Using three-dimensional eccentric structure ,body ring structure or the use of multi-level flexible metal ring, so that the same butterfly valve plate sealing surface contacts are reliable ,can be achieved without leakage of bubble seal.
2) Unique structure, operation flexible, labor-saving, convenience, long service life.
3) High temperature resistance, corrosion resistance, wear-resistant three-dimensional eccentric
