Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made of steel instead of iron
Steel butterfly valves fall under the steel subcategory within the same hand-operated group, distinguished by base material.
If not hand-operated, e.g., actuated
Power-operated or solenoid butterfly valves are classified separately from hand-operated ones.
If imported as parts like discs or shafts only
Individual components or parts of valves are classified in the parts heading rather than complete appliances.
