Semi-formal axiom (Aristotelian)
Axiom type
LLM classification basis: function-based → ≡
ISO 15926-4 grounds identity in design intent ('designed to act quickly'), a capacity/function-oriented criterion rather than a named physical mechanism. This matches the existing ontology's precedent for 'Rapid*Function' naming: blow down valve is genus=Valve, function=RapidDepressurizationFunction, axiom_mode='equivalent'. Tertiary evidence (quarter-turn valve family: ball/plug/butterfly) explains one common way the function is physically realized, but is not itself asserted as a structural condition here, since it describes a related term rather than a verbatim structural claim about 'quick acting valve' itself.

Identity-Giving Function
✓ done
RapidActuationFunction → RapidActuationProcess ⊑ FlowControl
▼
COPI-Core operation
FlowControl via process parent FlowControl
LLM rationale:
The identity-giving trait stated by the primary source is the design intent for speed of actuation itself ('designed to act quickly'), not a specific mechanism. FlowControlFunction (borne by the genus Valve) is the genuine supertype every valve function specializes; RapidActuationFunction narrows it by an actuation-speed criterion, following the same pattern as the already-enriched RapidDepressurizationFunction (blow down valve).

Genus Proximus

Genus (genus proximum)
Most specific superclass — may be a domain class like "Valve" or an IOF-Core root.
BFO/IOF-Core Root
bfo:Object branch
bfo:ObjectAggregate branch
bfo:ImmaterialEntity branch
LLM rationale:
parent_candidates lists ARTEFACT and VALVE (already enriched, genus_bfo_root=MaterialArtifact); VALVE is the most specific genuine supertype and matches the primary definition verbatim ('is an ARTEFACT and a VALVE that is designed to act quickly').

Conditions that distinguish
Quick Acting Valve
from sibling classes under genus
Valve.
Only what is not already entailed by the genus.
Differentia expression
Differentia (natural language)
LLM rationale:
Minimal functional addition beyond the generic Valve's FlowControlFunction. No structural condition is added because the primary source states this purely as a design-intent/functional criterion, and no source available names a specific mechanism as part of the definition of THIS term.

Necessary Parts
✓ done
no necessary parts
▼
Consider part-whole relations beyond subsumption:
hasComponentPartAtAllTimes (universal, structurally essential)
· hasComponentPartAtSomeTime (contingent, optional component)
LLM rationale:
No necessary parts are asserted. Tertiary evidence associates fast actuation with the quarter-turn/part-turn mechanism family (ball, plug, butterfly closures) as an empirical engineering correlation, but ISO 15926-4's own definition of QUICK ACTING VALVE names no component, and the tertiary sources describe the general 'quarter-turn valve' concept by name, not 'quick acting valve' -- asserting a specific closure mechanism as a necessary part here would overreach beyond what is grounded for this exact term.

Process Participation Signature ⟨I, O, T⟩
✓ done
PortionOfFluid → PortionOfFluid
▼
Inputs (I)
Outputs (O)
Transformation (T)
LLM rationale:
Same fluid-control signature as generic Valve and its already-enriched siblings (manual valve, self-operating valve) which also reuse 'flow_regulation' despite differing in actuation mechanism/source -- actuation speed does not change the ontological nature of the transformation, only its temporal profile.
