Duplex ball valves have the advantages of both ferritic stainless steel and austenitic stainless steel: austenitic stainless steel reduces the brittleness, maintains excellent toughness and weldability; ferritic stainless steel improves the yield strength, intergranular corrosion resistance and chloride stress corrosion resistance. Weidouli provides a whole range of high-class, customizable and innovative duplex ball valves. If you want to buy duplex ball valve in bulk, please feel free to contact us.
