Zirconium Plug Valve
WDL Zirconium Plug Valve provides fast quarter-turn isolation in compact process piping for acetic and formic acid processing and selected sulfuric acid systems. Connections, trim and operation are selected to the project conditions.
Description
Zirconium Plug Valve
WDL Zirconium Plug Valve provides fast quarter-turn isolation in compact process piping 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 | fast quarter-turn isolation in compact process piping |
| Connections | Flanged, threaded or welded |
| Operation | Lever, gearbox, pneumatic or electric actuator |
| Design basis | API 599, API 6D, ASME B16.34 or project standard |
Typical Applications
- Acetic and formic acid processing
- Selected sulfuric acid systems
- Chemical reactors and transfer lines
- Frequent on-off service
- Chemical transfer and distribution
Selection Notes
Fluoride-containing media, hydrofluoric acid and some oxidizing halides require special review because they can attack zirconium.
Confirm the plug style, cavity control, sleeve or seat material, operating torque and allowable leakage.
Frequently Asked Questions
Why select Zirconium for this plug 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.
