Duplex Stainless Steel Ball Valve
15 products found
A duplex stainless steel ball valve is a quarter-turn rotary valve constructed from a specialized alloy body (such as ASTM A890 or A182 F51) featuring a balanced 50/50 austenitic and ferritic microstructure. This advanced metallurgy provides double the mechanical yield strength of standard 316 stainless steel, along with elite resistance to chloride-induced pitting, crevice corrosion, and stress corrosion cracking. The internal polished ball rotates 90 degree against resilient or metal seats, providing straight-through, low-torque flow isolation under intense hydraulic loads. Offshore contractors and process engineers can secure superior mechanical strength and eliminate chloride stress cracking by importing duplex stainless steel ball valves directly from specialized manufacturers in China via our advanced B2B digital marketplace.
