Super Austenitic Gate Valve
WDL Super Austenitic Gate Valve provides full-bore on-off isolation with low pressure loss when open for seawater and brackish-water systems and flue-gas desulfurization. Connections, trim and operation are selected to the project conditions.
Description
Super Austenitic Gate Valve
WDL Super Austenitic Gate Valve provides full-bore on-off isolation with low pressure loss when open 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.
Design Options

- Main process isolation
- Full-bore pipeline service
Selection Notes
Verify the selected grade against chloride concentration, temperature, crevice conditions and pressure before manufacture.
Gate valves are normally selected for isolation rather than continuous throttling; confirm wedge, seat and stem design.
Frequently Asked Questions
Why select Super Austenitic Stainless Steel for this gate valve?
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.
What information is needed for selection?
Provide the size, pressure rating, medium composition, concentration, temperature, connection standard, operating method and required quantity.
