Hastelloy Discharge Valve
WDL Hastelloy Discharge Valve provides controlled draining from reactors, vessels and process tanks for mixed-acid chemical processing and wet chlorine and hypochlorite systems. Connections, trim and operation are selected to the project conditions.
Description
Hastelloy Discharge Valve
WDL Hastelloy Discharge Valve provides controlled draining from reactors, vessels and process tanks 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 | controlled draining from reactors, vessels and process tanks |
| Connections | Flanged or welded vessel and pipeline connections |
| Operation | Manual, pneumatic, electric or hydraulic actuator |
| Design basis | Project drawing, vessel interface and applicable pressure standard |
Typical Applications
- Mixed-acid chemical processing
- Wet chlorine and hypochlorite systems
- Fertilizer and pulp bleaching lines
- Reactor bottom discharge
- Tank draining and batch transfer
Selection Notes
Confirm the acid concentration, chloride content, temperature and contaminants before choosing C-276, C-22 or another Hastelloy grade.
Confirm the mounting orientation, dead-space limit, crystallization tendency, solids size and vessel nozzle dimensions.
Frequently Asked Questions
Why select Hastelloy Alloy for this discharge 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.
