Super Austenitic Check Valve
WDL Super Austenitic Check Valve provides automatic prevention of reverse flow for seawater and brackish-water systems and flue-gas desulfurization. Connections, trim and operation are selected to the project conditions.
Description
Super Austenitic Check Valve
WDL Super Austenitic Check Valve 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.
