1 Identity-Giving FunctionFunção Identitária
Function class
FlowControlFunction ⊑ DesignedFunction
Realized in
FlowControlProcess ⊑ PlannedProcess
Angle valves share the same identity-giving function as other valves - controlling fluid flow. The angle configuration is a structural differentia, not a functional one.
2 Genus DeterminationDeterminação do Gênero
Valvebfo:Object (BFO_0000030)
Valve is explicitly listed as a parent in the source hierarchies and is already enriched in our ontology. This is the most specific appropriate superclass - angle valve is clearly a subtype of valve distinguished by port geometry.
3 Differentia SpecificaDiferença Específica
∃hasPart.NonInlinePortArrangement

Has valve ports that are not in-line but arranged at an angle to each other.

The key differentiating feature is the non-inline port arrangement. This is what distinguishes angle valves from other valve types that maintain inline port geometry even when they redirect flow internally.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

The angle valve body with its non-inline port configuration is the essential distinguishing part. The flow control element is inherited from the valve genus.
