A self-operating valve is a valve that includes an internal means of operation (such as spring, gravity, fluid pressure, or counterbalance) and does not depend on an external source of energy for its actuation.
PT-BR
Uma válvula auto-operante é uma válvula que inclui um mecanismo interno de operação (como mola, gravidade, pressão do fluido ou contrapeso) e não depende de uma fonte externa de energia para seu acionamento.

Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
FlowControlFunction ⊑ DesignedFunction
Realized in
FlowControlProcess ⊑ PlannedProcess
As a valve, it inherits the generic flow control function. The self-operating mechanism is not a distinct function but a means of realizing the same flow control function without external energy.
2 Genus DeterminationDeterminação do Gênero
Valvebfo:Object (BFO_0000030)
Both sources explicitly classify this as a VALVE. The parent_candidates list shows 'VALVE' as already enriched in our ontology. This is the most specific appropriate superclass - self-operating valve is a specialized type of valve.
3 Differentia SpecificaDiferença Específica
∃hasComponentPartAtAllTimes.SelfOperatingMechanism ⊓ ∃bearerOf.EnergyIndependentOperationCapability

Has an internal operating mechanism (spring, gravity, fluid pressure, or counterbalance) and operates without depending on external energy sources.

The defining characteristic is the built-in operating mechanism that functions without external energy. This differentiates it from all other valve types that require external actuators or energy sources.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

Every self-operating valve must have the self-operating mechanism as its defining component, plus the basic valve components inherited from the genus.

TransformationTransformação
flow rate or pressure regulation without external energy input
Same basic fluid control signature as other valves, but the transformation is achieved through internal mechanisms rather than external actuation.
