Axiomatization Decision Log

Identity-Giving Function
Function class
ProcessControlledFlowFunction
⊑ FlowControlFunction
Realized in
ProcessControlledFlowProcess
⊑ PlannedProcess
The identity-giving function is ProcessControlledFlowFunction (already established for control valve in our ontology). This function involves modulating fluid flow in response to external control signals, which is what distinguishes control valves from manual valves or other valve types.

Genus Determination
ControlValve
From the parent candidates and ISO15926 definition, this is both a CONTROL VALVE and a BUTTERFLY VALVE. The most specific common genus is Valve. Both parent types (control valve and butterfly valve) are already enriched in our ontology as subtypes of Valve, which is enriched as a MaterialArtifact with FlowControlFunction.

Necessary Parts
| Part class | Parent | Relation |
|---|---|---|
| Actuator | Assembly | hasComponentPartAtAllTimes |
Parts combine the essential butterfly mechanism (rotating disc and shaft) with control valve requirements (actuator) in a standard valve body.

Process Participation Signature ⟨I, O, T⟩
Inputs (I)
PortionOfFluid
— liquid or gas
Outputs (O)
PortionOfFluid
— modulated flow rate and/or pressure
Transformation (T)
flow rate and pressure modulation through variable area restriction
Single input/output flow path with variable restriction based on disc position. The actuator responds to control signals to position the disc for desired flow characteristics.

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.
This is a constructive type that combines two existing differentia (butterfly mechanism + control function). Under OWA, providing sufficient conditions could lead to false positives where any valve with both a rotating disc and control capability would be classified as this specific type, even if it has additional specialized features or hybrid mechanisms.

Expert review — Accepted
Disjointness Axioms
BallControlValve
GateControlValve
GlobeControlValve
C1: BallControlValve, GateControlValve, GlobeControlValve. These control valve subtypes have incompatible closure mechanisms - ball vs disc vs gate vs globe closures are mutually exclusive physical implementations.
Cross-Standard Observations
Both ISO15926 and CFIHOS definitions are consistent, emphasizing both the butterfly mechanism and control capability with external actuation. CFIHOS adds explicit mention of actuator and external energy source.
