Duplex Steel Alloy Valve

Duplex Steel Valves are made from special alloy to work in corrosive conditions. It contains nickel and molybdenum. For some application copper is added. It is specially made to fulfill the requirement of challenging conditions of corrosive atmosphere. It is easy to use and easy to repair valve. Repairing of valves is also too simple due to easy replacement of the seats and gland packing.
