Duplex & Super Duplex Stainless Steel Valves
Duplex and super duplex stainless steel valves are highly resistant to corrosion and mechanical stress, making them ideal for demanding industries and applications operating in aggressive environments. Compared with conventional austenitic stainless steel, duplex and super duplex stainless steel offer higher strength, improved stress corrosion cracking resistance, and superior durability at high temperature conditions.
These valves provide excellent protection against chloride induced corrosion, including chloride stress corrosion cracking, as well as pitting and crevice corrosion, ensuring long service life in harsh service. As corrosion resistant solutions, they are widely used in oil gas, power generation, the marine industry, and desalination plants, where exposure to seawater, chemicals, and high salinity is common.
Available in multiple valve types, including ball valve designs, duplex and super duplex stainless steel valves deliver reliable performance, structural integrity, and consistent sealing in critical fluid control systems across severe operating conditions.
