Super Austenitic Ball Valve
WDL Super Austenitic Ball Valve provides quarter-turn isolation with a direct flow path and tight shutoff for seawater and brackish-water systems and flue-gas desulfurization. Connections, trim and operation are selected to the project conditions.
Description
Super Austenitic Ball Valve
WDL Super Austenitic Ball Valve provides quarter-turn isolation with a direct flow path and tight shutoff 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.
