WDL Duplex Discharge Valve<\/strong> provides controlled draining from reactors, vessels and process tanks for process systems that need high strength with resistance to chloride pitting and stress-corrosion cracking. Duplex stainless steel combines austenitic and ferritic phases for chloride service that requires higher strength than 300-series stainless steel.<\/p>\n<\/section>\n

    Choose 2205, 2507 or another grade from chloride level, temperature, pressure and required pitting resistance.<\/p>\n

    Confirm the mounting orientation, dead-space limit, crystallization tendency, solids size and vessel nozzle dimensions.<\/p>\n<\/section>\n

    Why select Duplex Stainless Steel for this discharge valve?<\/h3>\n

    Duplex stainless steel combines austenitic and ferritic phases for chloride service that requires higher strength than 300-series stainless steel. Final suitability depends on the complete process conditions and the selected valve trim.<\/p>\n
