Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
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.
2 Genus DeterminationDeterminação do Gênero
control valvebfo:Object (BFO_0000030)
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.
3 Differentia SpecificaDiferença Específica
∃hasComponentPartAtAllTimes.RotatingDisc ⊓ ∃bearerOf.ProcessControlledFlowFunction ⊓ ∃hasComponentPartAtAllTimes.Actuator

Has a rotating disc closure mechanism, bears a process-controlled flow function responding to external signals, and includes an actuator for remote operation.

The differentia combines the constructive aspect (rotating disc mechanism from butterfly valve) with the functional aspect (process-controlled flow from control valve) plus the actuator component that enables automated operation. This is minimal and distinguishing.

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.

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.
