Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
BinaryFlowControlFunction ⊑ ProcessControlledFlowFunction
Realized in
BinaryFlowControlProcess ⊑ ProcessControlledFlowProcess
The identity-giving function is the ability to provide binary (on/off) flow control in response to control signals, with only two defined positions. This is a specialization of ProcessControlledFlowFunction that restricts the control to discrete rather than continuous positioning.
2 Genus DeterminationDeterminação do Gênero
control valvebfo:Object (BFO_0000030)
From the parent candidates, 'control valve' is already enriched and is the most specific appropriate superclass. The concept is explicitly defined as 'a control valve' in the source definition. 'INSTRUMENTATION ITEM' is too broad and not equipment-specific.
3 Differentia SpecificaDiferença Específica
∃bearerOf.BinaryFlowControlFunction

Has only two defined positions, being fully open and fully closed, rather than continuous variable positioning.

The binary control characteristic is the key differentia - while all control valves respond to control signals, on-off control valves are specifically restricted to two discrete positions rather than continuous positioning capability.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

On-off control valves inherit standard valve parts (body, actuator) from the control valve genus. The key additional part is a binary positioning mechanism that restricts operation to only fully open or fully closed positions.

InputsEntradas
{'type': 'FluidPortion', 'count': 1, 'constraints': 'any process fluid'}, {'type': 'ControlSignal', 'count': 1, 'constraints': 'binary command signal'}
OutputsSaídas
{'type': 'FluidPortion', 'count': 1, 'constraints': 'same fluid, flow either fully allowed or fully blocked'}
TransformationTransformação
binary flow control - fluid flow is either completely enabled or completely blocked based on binary control input
The signature reflects the binary nature of the control - unlike continuously variable control valves, the output flow state has only two possible conditions corresponding to the two valve positions.
