Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
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.
2 Genus DeterminationDeterminação do Gênero
Valvebfo:Object (BFO_0000030)
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.
3 Differentia SpecificaDiferença Específica
∃hasComponentPartAtAllTimes.LinearMotionClosure ⊓ ∃hasComponentPartAtAllTimes.NormalSeat

Globe valves are distinguished by having a closure member (disc or plug) that operates with linear motion perpendicular to a seat that is oriented normal to the flow path.

The linear motion normal to the seat is the defining structural characteristic across all sources. This differentiates from other valve mechanisms like rotational (ball, butterfly) or parallel sliding (gate) motions.

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.
