Hastelloy Gate Valve
WDL Hastelloy Gate Valve provides full-bore on-off isolation with low pressure loss when open for mixed-acid chemical processing and wet chlorine and hypochlorite systems. Connections, trim and operation are selected to the project conditions.
Description
Hastelloy Gate Valve
WDL Hastelloy Gate Valve provides full-bore on-off isolation with low pressure loss when open 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 | 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
- Mixed-acid chemical processing
- Wet chlorine and hypochlorite systems
- Fertilizer and pulp bleaching lines
- Main process isolation
- Full-bore pipeline service
Selection Notes
Confirm the acid concentration, chloride content, temperature and contaminants before choosing C-276, C-22 or another Hastelloy grade.
Gate valves are normally selected for isolation rather than continuous throttling; confirm wedge, seat and stem design.
Frequently Asked Questions
Why select Hastelloy Alloy for this gate 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.
Send the process datasheet to WDL for material review, dimensional confirmation and quotation.
