Axiomatization Decision Log

Identity-Giving Function
Function class
ProcessControlledFlowFunction
⊑ FlowControlFunction
Realized in
ProcessControlledFlowProcess
⊑ PlannedProcess
A globe control valve's identity is grounded in its designed function to control fluid flow in response to process control signals. This is the same identity-giving function as control valve (already enriched), which this concept specializes with globe-specific construction.

2
Genus Determination
ControlValve
From the parent candidates, both 'control valve' and 'globe valve' are already enriched. Since this is a 'globe control valve', the most specific genus is 'control valve' - it is primarily a control valve that happens to use globe construction. This follows the functional-primary classification where constructive aspects are differentiating features of functional categories.

Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
These parts are specific to globe construction and necessary for all globe control valve instances, beyond the generic parts inherited from control valve genus.

Process Participation Signature ⟨I, O, T⟩

Outputs (O)
PortionOfFluid
— flow rate and pressure controlled per control signal
Transformation (T)
modulated flow control with pressure drop through angled flow path
Single inlet to single outlet with modulated flow control characteristic of control valves, but with the specific pressure drop and flow characteristics of globe valve geometry.

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 because this is a constructive subtype (both classification basis). The structural differentia (globe body + linear closure) provides strong necessary conditions, but declaring sufficiency under OWA could lead to unwanted automatic classification of specialized equipment that contains globe mechanisms but should not be categorized as standard globe control valves.

Expert review — Accepted
Disjointness Axioms
BallControlValve
ButterflyControlValve
GateControlValve
C1: ball control valve, butterfly control valve, gate control valve. These constructive control valve subtypes have incompatible closure mechanisms: globe uses linear motion through angled flow path, ball uses rotational spherical closure, butterfly uses rotating disc, gate uses sliding gate with straight-through flow.
Cross-Standard Observations
Both ISO 15926 and CFIHOS agree on the dual nature (control valve + globe valve). ISO 15926 adds INSTRUMENTATION ITEM classification, which aligns with the control function. CFIHOS mentions 'actuated valve' which is redundant since control valves are by definition actuated.
