Definition (PT-BR)
Semi-formal axiom (Aristotelian)
Axiom type
LLM classification basis: both
This concept combines both functional and constructive classification axes. The functional parent is 'control valve' (process-controlled flow function with actuator response to external signals), and the constructive differentia is the choke mechanism (pressure reduction through flow restriction geometry). A choke control valve is simultaneously a control valve (functional) and a choke valve (constructive).
