Tantalum Gate Valve
WDL Tantalum Gate Valve provides full-bore on-off isolation with low pressure loss when open for hydrochloric acid equipment and sulfuric acid process lines. Connections, trim and operation are selected to the project conditions.
Description
Tantalum Gate Valve
WDL Tantalum Gate Valve provides full-bore on-off isolation with low pressure loss when open for process systems that need acid resistance in selected highly corrosive chemical processes. Tantalum-wetted construction is considered for severe acid service when corrosion allowance is not an acceptable solution.
Design Options
| Item | Available specification |

Typical Applications
- Hydrochloric acid equipment
- Sulfuric acid process lines
- Acid recovery systems
- Main process isolation
- Full-bore pipeline service
Selection Notes
Hydrofluoric acid, fluoride salts and strong alkaline media require separate compatibility review and are not default tantalum applications.
Gate valves are normally selected for isolation rather than continuous throttling; confirm wedge, seat and stem design.
Frequently Asked Questions
Why select Tantalum for this gate valve?
Tantalum-wetted construction is considered for severe acid service when corrosion allowance is not an acceptable solution. 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.
