Hastelloy Ball Valve
WDL Hastelloy Ball Valve provides quarter-turn isolation with a direct flow path and tight shutoff for mixed-acid chemical processing and wet chlorine and hypochlorite systems. Connections, trim and operation are selected to the project conditions.
Description
Hastelloy Ball Valve
WDL Hastelloy Ball Valve provides quarter-turn isolation with a direct flow path and tight shutoff 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 | quarter-turn isolation with a direct flow path and tight shutoff |
| Connections | Flanged, threaded, socket-welded or butt-welded |
| Operation | Lever, gearbox, pneumatic or electric actuator |
| Design basis | API 608, API 6D, ASME B16.34 or project standard |
Typical Applications
- Mixed-acid chemical processing
- Wet chlorine and hypochlorite systems

- Automated emergency or batch shutoff
Selection Notes
Confirm the acid concentration, chloride content, temperature and contaminants before choosing C-276, C-22 or another Hastelloy grade.
Confirm floating or trunnion design, cavity relief, seat material, fire-safe requirement and bore size.
Frequently Asked Questions
Why select Hastelloy Alloy for this ball 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?
Provide the size, pressure rating, medium composition, concentration, temperature, connection standard, operating method and required quantity.
