Nickel Ball Valve
WDL Nickel Ball Valve provides quarter-turn isolation with a direct flow path and tight shutoff for caustic soda systems and alkali concentration equipment. Connections, trim and operation are selected to the project conditions.
Description
Nickel Ball Valve
WDL Nickel Ball Valve provides quarter-turn isolation with a direct flow path and tight shutoff for process systems that need resistance in caustic alkali and selected reducing or neutral media. Commercially pure Nickel 200/201 is commonly selected for caustic alkali and controlled reducing or neutral environments.
Design Options

Selection Notes
Nickel 201 is normally considered for higher-temperature exposure; oxidizing acids and sulfur-bearing media require another material review.
Confirm floating or trunnion design, cavity relief, seat material, fire-safe requirement and bore size.
Frequently Asked Questions
Why select Nickel 200/201 for this ball valve?
Commercially pure Nickel 200/201 is commonly selected for caustic alkali and controlled reducing or neutral 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.
Send the process datasheet to WDL for material review, dimensional confirmation and quotation.
