WDL Super Austenitic Check Valve<\/strong> provides automatic prevention of reverse flow for process systems that need improved pitting and crevice-corrosion resistance in chloride service. Super austenitic stainless steel provides higher nickel, molybdenum and nitrogen content than standard 316L for demanding chloride environments.<\/p>\n<\/section>\n

    Why select Super Austenitic Stainless Steel for this check valve?<\/h3>\n

    Super austenitic stainless steel provides higher nickel, molybdenum and nitrogen content than standard 316L for demanding chloride environments. Final suitability depends on the complete process conditions and the selected valve trim.<\/p>\n
