Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
FlowControlFunction ⊑ DesignedFunction
Realized in
FlowControlProcess ⊑ PlannedProcess
Butterfly valves share the generic valve function of controlling fluid flow. This is the identity-giving function inherited from the Valve genus, not a specialized function unique to butterfly valves.
2 Genus DeterminationDeterminação do Gênero
Valvebfo:Object (BFO_0000030)
All sources classify butterfly valve as a subtype of valve (explicitly 'rotary valve' in ISO 15926, CFIHOS, and POSC Caesar). The Valve class is already enriched in our ontology with function FlowControlFunction and genus MaterialArtifact, making it the most specific appropriate superclass.
3 Differentia SpecificaDiferença Específica
∃hasComponentPartAtAllTimes.DiscTypeClosure ⊓ ∃hasComponentPartAtAllTimes.TransverseRotationAxis

Has a disc-type closure member that rotates on an axis transverse to the flow direction.

The consistent defining characteristic across all sources is the disc-type closure member with transverse rotation axis. This is the minimal structural differentia that distinguishes butterfly valves from other valve subtypes under the same genus.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

These parts constitute the essential structural elements that enable the characteristic disc rotation mechanism of butterfly valves, beyond the basic valve body inherited from the genus.

BallValve GateValve GlobeValve
C1: BallValve, GateValve, GlobeValve. These valve types have incompatible closure mechanisms: ball valves use spherical closures, gate valves use sliding linear motion, globe valves use linear stem motion. The physical mechanisms are mutually exclusive.
