Dual phase steel DBB double blocking double discharge ball valve

structural form

The double block double discharge ball valve is a double ball structure, equivalent to two single ball valves connected together, each ball has its own valve seat and stem.

22052507 duplex stainless steel combines the advantages of ferritic stainless steel and austenitic stainless steel. The presence of austenite reduces the brittleness and tendency for crystal growth of high Cr ferrite, while maintaining excellent toughness and weldability; The presence of ferrite enhances the yield strength, intergranular corrosion resistance, and chloride stress corrosion resistance of austenite.
