Axiom type
LLM classification basis: structure-based → ⊑
Identity is given by the physical configuration specific to globe valves — the globular body shape that accommodates the perpendicular flow path and disc closure mechanism characteristic of globe valve internal geometry. This is a structural/geometric differentia, not a functional one.

EnclosureFunction → EnclosureProcess ⊑ MaterialContainment
▼
COPI-Core operation
MaterialContainment via process parent MaterialContainment
LLM rationale:
A globe valve body, like all valve bodies, has the generic function of providing structural enclosure for the valve's internal components and directing fluid flow. This is the same basic function as any valve body — the differentia comes from the specific globular geometry.

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:
The ISO 15926-4 definition explicitly states 'A <GLOBE VALVE BODY> is a <VALVE BODY> of a globe valve.' The parent_candidates list includes 'VALVE BODY' from iso15926, making this the obvious genus proximum. A valve body is a structural component (MaterialArtifact) that houses valve internals.

Differentia expression
Differentia (natural language)
LLM rationale:
The globular geometry is the key structural differentia that distinguishes globe valve bodies from other valve body types. This geometric configuration enables the characteristic perpendicular flow path and accommodates the disc-and-seat closure mechanism specific to globe valves.

Necessary Parts
✓ done
no necessary parts
▼
Consider part-whole relations beyond subsumption:
hasComponentPartAtAllTimes (universal, structurally essential)
· hasComponentPartAtSomeTime (contingent, optional component)
LLM rationale:
No component terms are provided in the Known Component Terms list, and the source definition is minimal, only identifying the structural relationship to globe valves without specifying internal parts. The necessary parts would be inherited from the valve body genus or specified at more detailed subtype levels.

Process Participation Signature ⟨I, O, T⟩
✓ done
PortionOfFluid → PortionOfFluid
▼
Inputs (I)
Outputs (O)
Transformation (T)
LLM rationale:
As a valve body component, the process signature involves fluid passage, but the globe-specific geometry creates a characteristic perpendicular flow redirection that distinguishes it from straight-through valve body types.
