Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
FlowControlFunction ⊑ DesignedFunction
Realized in
FlowControlProcess ⊑ PlannedProcess
Gate valves share the same identity-giving function as other valves - controlling fluid flow. The function FlowControlFunction is already established in the enriched valve class. Gate valves do not have a distinct function subtype; their identity comes from their structural mechanism.
2 Genus DeterminationDeterminação do Gênero
Valvebfo:Object (BFO_0000030)
All source definitions explicitly state that gate valve 'is a valve'. The parent_candidates include VALVE from iso15926, and Valve is already enriched in our ontology with function FlowControlFunction and genus MaterialArtifact. This is the most specific appropriate superclass.
3 Differentia SpecificaDiferença Específica
∃hasComponentPartAtAllTimes.GateClosure ⊓ ∃hasComponentPartAtAllTimes.LinearActuationMechanism

Has a gate or disc closure member that moves linearly parallel to the seat plane, transverse to the flow direction.

The differentia captures the defining structural characteristics: the gate closure member and its linear motion mechanism. This distinguishes gate valves from all other valve types which use different closure mechanisms (rotating ball, butterfly disc, needle, etc.).
4 Necessary PartsPartes Necessárias
Part classParentRelation
ValveSeatMaterialArtifacthasComponentPartAtAllTimes
These parts define the essential structural components that make a gate valve function with its characteristic linear sliding motion. The gate closure and linear actuation mechanism are unique to gate valves, while seats are common to valves but have specific geometric requirements for gate valve operation.

TransformationTransformação
flow rate modification by linear gate positioning
Gate valves typically operate as on/off devices (fully open or fully closed as noted in onepetro definition) but can provide flow control through gate positioning. Single inlet/outlet with mechanical flow control transformation.
Disjoint WithDisjunto com
BallValve ButterflyValve NeedleValve
C1: BallValve, ButterflyValve, NeedleValve. Gate valves use linear sliding motion which is mechanically incompatible with the rotary motion of ball valves and butterfly valves, and with the axial needle motion of needle valves. These represent mutually exclusive closure mechanisms.
