Duplex Valve Vs Super Duplex Valve
Duplex Valve
Duplex stainless steel valves are widely used in various industries such as chemical industry, seawater desalination, shipbuilding, petrochemical industry, oil, and gas industry. DSS is also known as S31803, S32205, A351 CD3MN, ASTM A182 F51 and 1.4470. Check Chemical Properties of Duplex Valves
