1 Identity-Giving FunctionFunção Identitária
Function class
FlowControlFunction ⊑ DesignedFunction
Realized in
FlowControlProcess ⊑ PlannedProcess
A block and bleed valve shares the same identity-giving function as all valves - controlling flow. The blocking and bleeding capabilities are realized through its structural configuration, not through a distinct function type.
2 Genus DeterminationDeterminação do Gênero
Valvebfo:Object (BFO_0000030)
Block and bleed valve is clearly a specialized type of valve. The parent candidates include 'manual valve' which is enriched, but 'Valve' is the more appropriate direct superclass since block and bleed valves can be manual or actuated. Both ISO 15926 and the functional definition confirm this is a valve subtype.
3 Differentia SpecificaDiferença Específica
∃hasComponentPartAtAllTimes.SingleSeat ⊓ ∃hasComponentPartAtAllTimes.BleederLine ⊓ ∃hasComponentPartAtAllTimes.BleederValve

Has exactly one seat for sealing and includes a bleeder line with valve tapped into the bonnet for venting the downstream side when blocked.

The defining structural characteristics are the single seat design and the integrated bleeder system. This differentiates it from other valve types that either lack bleeding capability or have different seat configurations.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

These three components are constitutive of the block and bleed valve design. The single seat provides the blocking function, while the bleeder line and valve enable safe venting of downstream pressure.

TransformationTransformação
flow isolation with controlled bleeding capability
The valve can isolate flow (block function) while simultaneously allowing controlled release of downstream pressure through the bleeder system. This creates two output streams when bleeding.
