Monel Gate Valve
WDL Monel Gate Valve provides full-bore on-off isolation with low pressure loss when open for hydrofluoric acid processing and marine and seawater systems. Connections, trim and operation are selected to the project conditions.
Description
Monel Gate Valve
WDL Monel Gate Valve provides full-bore on-off isolation with low pressure loss when open for process systems that need resistance to hydrofluoric acid, seawater and selected reducing media. Monel 400 is a nickel-copper alloy used for controlled hydrofluoric acid, marine and reducing chemical duties.

Selection Notes
Aeration, oxidizing salts, temperature and impurities can change Monel 400 corrosion behavior and must be included in the material review.
Gate valves are normally selected for isolation rather than continuous throttling; confirm wedge, seat and stem design.
Frequently Asked Questions
Why select Monel 400 for this gate valve?
Monel 400 is a nickel-copper alloy used for controlled hydrofluoric acid, marine and reducing chemical duties. 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.
