Zirconium Gate Valve
WDL Zirconium Gate Valve provides full-bore on-off isolation with low pressure loss when open for acetic and formic acid processing and selected sulfuric acid systems. Connections, trim and operation are selected to the project conditions.
Description
Zirconium Gate Valve
WDL Zirconium Gate Valve provides full-bore on-off isolation with low pressure loss when open for process systems that need resistance to many strong acids and corrosive chemical mixtures. Zirconium is used for severe acid duties where stainless steels and many nickel alloys cannot provide an acceptable corrosion rate.
Design Options
| Item | Available specification |
|---|---|
| Material | Zirconium 702, 705 or project-specified grade |
| Function | full-bore on-off isolation with low pressure loss when open |
| Connections | Flanged or butt-welded |
| Operation | Handwheel, gearbox, pneumatic or electric actuator |
| Design basis | API 600, API 603, API 6D or ASME B16.34 |
Typical Applications
- Acetic and formic acid processing
- Selected sulfuric acid systems
- Chemical reactors and transfer lines
- Main process isolation
- Full-bore pipeline service
Selection Notes
Fluoride-containing media, hydrofluoric acid and some oxidizing halides require special review because they can attack zirconium.
Gate valves are normally selected for isolation rather than continuous throttling; confirm wedge, seat and stem design.
Frequently Asked Questions
Why select Zirconium for this gate valve?
Zirconium is used for severe acid duties where stainless steels and many nickel alloys cannot provide an acceptable corrosion rate. 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.
