Axiomatization Decision Log
1
Identity-Giving Function
Function class
EnclosureFunction
⊑ DesignedFunction
Realized in
EnclosureProcess
⊑ MaterialContainment
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.
2
Genus Determination
ValveBody
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.
3
Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
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.
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
PortionOfFluid
— any phase fluid requiring controlled passage through globe valve geometry
Outputs (O)
PortionOfFluid
— same fluid with modified flow characteristics due to perpendicular flow path geometry
Transformation (T)
fluid passage redirected through perpendicular flow path characteristic of globular chamber geometry
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.
5
Axiom Mode Decision
Necessary conditions only
— modelled as a primitive universal
(⊑, SubClassOf). Identity is grounded in designed
function and cannot be reduced to a property checklist.
Constructive type defined by structural geometry. Under OWA, asserting equivalence based on globular geometry alone could lead to false classifications of complex assemblies or hybrid components that contain globular elements but should not be classified as standard globe valve bodies.
Cross-Standard Observations
Only one source (ISO 15926-4) provides a definition. The definition is minimal, focusing on the taxonomic relationship rather than detailed structural or functional characteristics.
