Zirconium Globe Valve
WDL Zirconium Globe Valve provides controlled throttling and positive process isolation for acetic and formic acid processing and selected sulfuric acid systems. Connections, trim and operation are selected to the project conditions.
Description
Zirconium Globe Valve
WDL Zirconium Globe Valve provides controlled throttling and positive process isolation 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 | controlled throttling and positive process isolation |
| Connections | Flanged, threaded, socket-welded or butt-welded |
| Operation | Handwheel, gearbox, pneumatic or electric actuator |
| Design basis | API 623, BS 1873, ASME B16.34 or project standard |
Typical Applications
- Acetic and formic acid processing
- Selected sulfuric acid systems
- Chemical reactors and transfer lines
- Flow and pressure regulation
- Chemical dosing and utility control
Selection Notes
Fluoride-containing media, hydrofluoric acid and some oxidizing halides require special review because they can attack zirconium.
Provide the required flow coefficient, pressure drop, flow direction, trim design and shutoff requirement.
Frequently Asked Questions
Why select Zirconium for this globe 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.
