Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
ProcessControlledFlowFunction ⊑ FlowControlFunction
Realized in
ProcessControlledFlowProcess ⊑ PlannedProcess
The identity-giving function is process-controlled flow regulation, inherited from control valve. This function distinguishes control valves from manual valves by requiring responsiveness to external control signals for automated process control.
2 Genus DeterminationDeterminação do Gênero
control valvebfo:Object (BFO_0000030)
ControlValve is the most specific appropriate superclass, already enriched in our ontology. Ball control valve is a subtype that adds the constructive constraint of ball closure mechanism to the functional control valve category. BallValve would be too narrow as genus since it lacks the control function identity.
3 Differentia SpecificaDiferença Específica
∃hasComponentPartAtAllTimes.BallClosure ⊓ ∃hasComponentPartAtAllTimes.RotaryActuator

Has a spherical ball closure element that rotates to control flow and a rotary actuator for precise positioning.

The differentia captures the constructive constraint: ball closure mechanism (spherical element) with rotary actuation. The control function is inherited from ControlValve genus. Both BallClosure and RotaryActuator are necessary to distinguish from other control valve subtypes.

No necessary parts recorded.

These parts are universal across all ball control valve instances and constitute the essential structural elements for the ball closure mechanism with automated control capability.

flow rate modulation through rotary ball positioning
Single inlet/outlet signature with flow modulation transformation. Ball rotation varies the flow area to achieve precise flow control in response to control signals.

GateControlValve GlobeControlValve ButterflyControlValve
C1: gate control valve, globe control valve, butterfly control valve. These control valve subtypes have incompatible closure mechanisms: sliding gate vs rotating ball vs rotating disc. The structural mechanisms are mutually exclusive.
