Tantalum Check Valve
WDL Tantalum Check Valve provides automatic prevention of reverse flow for hydrochloric acid equipment and sulfuric acid process lines. Connections, trim and operation are selected to the project conditions.
Description
Tantalum Check Valve
WDL Tantalum Check Valve provides automatic prevention of reverse flow 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

Selection Notes
Hydrofluoric acid, fluoride salts and strong alkaline media require separate compatibility review and are not default tantalum applications.
Confirm installation direction, minimum flow, cracking pressure, slam risk and allowable pressure drop.
Frequently Asked Questions
Why select Tantalum for this check 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.
