Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
ProcessControlledFlowFunction ⊑ FlowControlFunction
Realized in
ProcessControlledFlowProcess ⊑ PlannedProcess
The identity-giving function is to modify/regulate fluid flow rate in response to control signals. This distinguishes control valves from other valve types that may open/close but lack the modulation capability for process control.
2 Genus DeterminationDeterminação do Gênero
valvebfo:Object (BFO_0000030)
From the parent_candidates, VALVE is the most specific appropriate superclass. All definitions consistently show control valve as a subtype of valve with additional control capabilities. FINAL CONTROL FUNCTION is too narrow and functional rather than material. Valve represents the physical artifact that provides the structural foundation for flow control.
3 Differentia SpecificaDiferença Específica
∃hasComponentPartAtAllTimes.Actuator

A control valve is distinguished from other valves by having an actuator as a permanent component part, which drives the closure element in response to external control signals to modulate flow.

4 Necessary PartsPartes Necessárias

No necessary parts recorded.

Control valves universally require an actuator for automated positioning and a flow control element for physical flow modulation. The specific type of control element varies by constructive subtype but some form is always present.

TransformationTransformação
flow rate modulation based on control signal input
Control valves receive process fluid and control signals, outputting fluid with modulated flow characteristics based on the control input. This signature distinguishes them from manual valves or simple on-off valves.
