Natural Language Definition
EN
A quick acting valve is a valve designed to open or close substantially faster than a conventional multi-turn valve of the same service, so as to admit or interrupt flow with minimal actuation delay.
PT-BR
Uma valvula de acao rapida e uma valvula projetada para abrir ou fechar substancialmente mais rapido que uma valvula multivolta convencional de mesmo servico, de modo a admitir ou interromper o fluxo com atraso minimo de acionamento.
Formal Axioms
Semi-formal (Aristotelian)
Every quick acting valve is a valve that bears a rapid actuation function, and conversely.

Axiomatization Decision Log
1
Identity-Giving Function
Function class
RapidActuationFunction
⊑ FlowControlFunction
Realized in
RapidActuationProcess
⊑ FlowControl
The identity-giving trait stated by the primary source is the design intent for speed of actuation itself ('designed to act quickly'), not a specific mechanism. FlowControlFunction (borne by the genus Valve) is the genuine supertype every valve function specializes; RapidActuationFunction narrows it by an actuation-speed criterion, following the same pattern as the already-enriched RapidDepressurizationFunction (blow down valve).
2
Genus Determination
Valve
parent_candidates lists ARTEFACT and VALVE (already enriched, genus_bfo_root=MaterialArtifact); VALVE is the most specific genuine supertype and matches the primary definition verbatim ('is an ARTEFACT and a VALVE that is designed to act quickly').
3
Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
No necessary parts are asserted. Tertiary evidence associates fast actuation with the quarter-turn/part-turn mechanism family (ball, plug, butterfly closures) as an empirical engineering correlation, but ISO 15926-4's own definition of QUICK ACTING VALVE names no component, and the tertiary sources describe the general 'quarter-turn valve' concept by name, not 'quick acting valve' -- asserting a specific closure mechanism as a necessary part here would overreach beyond what is grounded for this exact term.
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
PortionOfFluid
— any phase - liquid, gas, or multiphase, same as generic Valve
Outputs (O)
PortionOfFluid
— same fluid, admitted or blocked depending on valve position
Transformation (T)
flow admitted or interrupted through rapid actuation of the valve's closure member, without energy addition to the fluid
Same fluid-control signature as generic Valve and its already-enriched siblings (manual valve, self-operating valve) which also reuse 'flow_regulation' despite differing in actuation mechanism/source -- actuation speed does not change the ontological nature of the transformation, only its temporal profile.
5
Axiom Mode Decision
Necessary + Sufficient
— modelled as a defined class
(≡, EquivalentClass). Automatic classification is
appropriate for this concept.
Cross-Standard Observations
Only ISO 15926-4 defines this exact term (no cross-source corroboration in terms.db). Secondary-tier standard sources (ASME B16.34, ISO 5211, AIChE CCPS Process Safety Glossary) were attempted but all returned HTTP 403 (paywalled/blocked); tertiary web-glossary sources (e4industrial.com, wermac.org -- 2 independent domains) confirm that the industry's related 'quarter-turn valve' category (ball/plug/butterfly) is described as fast-acting by virtue of its 90-degree actuation stroke, versus multi-turn valves (gate/globe). This is used only as interpretive context for the rationale fields above, not as a structural grounding for necessary_parts.
Reviewer Notes
Step 2b/2c (enrich-term skill, generation_path='skill_session'): secondary standard sources (ASME B16.34, ISO 5211, AIChE CCPS Process Safety Glossary) all returned HTTP 403. Fell back to 2 independent triangulated tertiary web-glossary sources (e4industrial.com, wermac.org) confirming the related 'quarter-turn valve' family (ball/plug/butterfly) is the common realisation of fast actuation -- used only as interpretive context, not as necessary_parts grounding, since it describes a related term rather than 'quick acting valve' verbatim.
