Axiomatization Decision Log
1 Identity-Giving Function
Function class
FlowControlFunction ⊑ DesignedFunction
Realized in
FlowControlProcess ⊑ FlowControl
Globe valves share the same identity-giving function as the general Valve class - controlling fluid flow. The differentia comes from the specific linear motion mechanism, not a unique function type. Reusing FlowControlFunction from already-enriched valve class.

Expert review — Accepted
2 Genus Determination
Valve
Valve is the most specific appropriate superclass, already enriched in the ontology with FlowControlFunction. All sources explicitly state 'globe valve is a valve'. Globe valve is a constructive subtype that inherits the flow control function but adds specific structural constraints.
✓
Expert review — Accepted
3 Necessary Parts
Part class Parent Relation
GlobeValveClosureMember MaterialArtifact hasComponentPartAtAllTimes
Parts focus on the structural elements that implement the defining linear motion mechanism normal to the flow path, distinguishing globe valves from other valve types.
✓
Expert review — Accepted
4 Process Participation Signature ⟨I, O, T⟩
Inputs (I)
PortionOfFluid — any phase
Outputs (O)
PortionOfFluid — same composition, potentially different flow rate
Transformation (T)
flow rate modulation through variable restriction
Globe valves modulate flow through linear positioning of closure member, providing variable restriction from fully open to fully closed positions. Single inlet/outlet with same fluid composition.

Expert review — Accepted
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.

Using necessary conditions for this constructive type. Under OWA, making the structural differentia sufficient could force classification of specialized equipment containing linear motion closures (like complex multi-way valves or custom manifolds) as standard globe valves when they may warrant distinct maintenance categories.
✓
Expert review — Accepted
Cross-Standard Observations
All four sources provide consistent definitions focusing on the linear motion mechanism and normal seat orientation. ISO 15926 and SLB provide slightly more detail about disc/piston alternatives and seat geometry. No significant conflicts across standards.
