Specialityvalve is best Duplex Steel Valve Manufacturer In India. Duplex Steel Valves are constructed from duplex grade steels. The microstructure of the duplex grade contains austenitic and ferritic phases, giving it high strength and corrosion resistance. Because of their metallurgy, these steels can be used in a variety of applications. This material is used to make valves that are dependable, strong, and corrosion resistant.

Duplex stainless-steel valves are classified into three types: standard duplex, super duplex, and lean duplex. Each of them outperforms the former in terms of corrosion and strength. Valves of various types, such as ball valves and gate valves, are used for specific purposes in an application. Duplex stainless steel butterfly valves are used in applications that require bidirectional flow control.
