WDL Duplex Gate Valve<\/strong> provides full-bore on-off isolation with low pressure loss when open 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

    Gate valves are normally selected for isolation rather than continuous throttling; confirm wedge, seat and stem design.<\/p>\n<\/section>\n

    Why select Duplex Stainless Steel for this gate 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
