Description
Hastelloy Plug Valve
WDL Hastelloy Plug Valve provides fast quarter-turn isolation in compact process piping for process systems that need corrosion resistance in mixed-acid and chloride-bearing process media. Hastelloy alloys are selected for chemical streams that combine chlorides with reducing or oxidizing conditions.
Design Options
| Item | Available specification |
|---|---|
| Material | Hastelloy C-276, C-22 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
- Mixed-acid chemical processing
- Wet chlorine and hypochlorite systems
- Fertilizer and pulp bleaching lines
- Frequent on-off service
- Chemical transfer and distribution
Selection Notes
Confirm the acid concentration, chloride content, temperature and contaminants before choosing C-276, C-22 or another Hastelloy grade.
Confirm the plug style, cavity control, sleeve or seat material, operating torque and allowable leakage.
Frequently Asked Questions
Why select Hastelloy Alloy for this plug valve?
Hastelloy alloys are selected for chemical streams that combine chlorides with reducing or oxidizing conditions. Final suitability depends on the complete process conditions and the selected valve trim.
What information is needed for selection?
