Axiomatization Decision Log
1
Identity-Giving Function
Function class
EnclosureFunction
⊑ DesignedFunction
Realized in
EnclosureProcess
⊑ MaterialContainment
As a valve body component, the check valve body's primary function is to enclose and house the check valve internals (disc, seat, spring, etc.) within a pressure-containing boundary. This is the generic enclosure function shared by all valve bodies.
2
Genus Determination
ValveBody
The source definition explicitly states 'A <CHECK VALVE BODY> is a <VALVE BODY> of a check valve'. ValveBody is the most specific appropriate superclass. ValveBody would be a MaterialArtifact (pressure-containing housing component) rather than Assembly as it is typically a single machined or cast component.
3
Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
No component terms are provided in the source standards for check valve body parts. The internal parts (disc, seat, spring, hinge pin) would be parts of the complete check valve assembly, not necessary parts of the valve body component itself. The valve body is typically a single cast or machined housing.
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
—
Outputs (O)
—
Transformation (T)
structural containment and protection of check valve internal mechanisms within pressure boundary
As a passive structural component (valve body), it does not have process inputs/outputs like the complete valve would have. Its process signature is purely containment - providing the housing structure that enables the check valve mechanism to function.
5
Axiom Mode Decision
Necessary conditions only
— modelled as a primitive universal
(⊑, SubClassOf). Identity is grounded in designed
function and cannot be reduced to a property checklist.
Constructive identity based on structural design for check valve accommodation. Under OWA, any housing designed for check valves could include specialized configurations, custom manifolds, or hybrid designs that should not be automatically classified as standard check valve bodies without domain expert validation of the structural differentia.
Cross-Standard Observations
Only one source (ISO 15926-4) provides the definition. The definition is minimal but clear in establishing the part-whole relationship with check valves and the subtype relationship with valve bodies.
