Our Super Duplex Ball Valves are constructed from high-performance alloys that include about 25% chromium, nickel, molybdenum, and nitrogen, all of which enhance their mechanical strength and corrosion resistance. They offer impressive tensile strength ranging from 800 to 1000 MPa, with yield strength nearly double that of standard austenitic stainless steels. Even in sub-zero temperatures, these valves maintain excellent toughness and ductility. Their advanced alloy composition ensures they resist chloride-induced stress corrosion cracking, localized corrosion, and erosion, making them a reliable choice for managing aggressive fluids in high-pressure systems.
