Duplex Globe Valves

The microstructure of the duplex stainless steel globe valve consists of a mixture of an austenitic phase and a ferrite phase. Therefore, the duplex steel has both austenitic and ferritic stainless steel properties.

The duplex globe valve uses stainless steel which has stronger resistance to corrosion than the commonly used grades of stainless steel valves, namely 304 valves and 316 valves. Duplex stainless steel valves are widely used in various industries such as the chemical industry, seawater desalination, shipbuilding, petrochemical industry, oil, and gas industry.

Advantages of Duplex Globe Valve

  • With a simple structure, duplex globe valves can be manufactured easily.

  • It is convenient to maintain the surface and property of a duplex globe valve.

  • The duplex globe valve has greater corrosion resistance in stress corrosion cracking.

  • At a rather lower price, duplex globe valves have low friction between the sealing surface and long life.
