Identity-Giving Function
Function class
FlowControlFunction
⊑ DesignedFunction
Realized in
FlowControlProcess
⊑ FlowControl
A solenoid valve is fundamentally a valve - its identity-giving function is controlling fluid flow. The solenoid is the actuation mechanism, but the core function remains flow control. This aligns with the existing FlowControlFunction used for other valve types in the ontology.

Genus Determination
Valve
From the parent candidates, 'Valve' is the most specific and appropriate genus. It is already enriched in our ontology with FlowControlFunction. 'ACTUATED VALVE' would be more specific but is not yet enriched and may be too restrictive for this fundamental level. The valve genus provides the flow control function foundation.

Necessary Parts
| Part class | Parent | Relation |
|---|---|---|
| SolenoidActuator | Actuator | hasComponentPartAtAllTimes |
These parts are universally required for solenoid valve operation: the solenoid provides electromagnetic actuation, electrical connections enable control, and the valve closure performs the flow control function.

Process Participation Signature ⟨I, O, T⟩
Inputs (I)
PortionOfFluid
— process fluid at inlet conditions
InformationContentEntity
— control signal to solenoid
Outputs (O)
PortionOfFluid
— controlled flow at outlet conditions
Transformation (T)
electrical signal transduction to mechanical valve positioning, enabling fluid flow control
Solenoid valves transform electrical control signals into mechanical valve positioning to control fluid flow. The electrical input distinguishes them from manually operated valves.

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.
Using necessary conditions because this is a constructive type where the solenoid mechanism is the distinguishing structural feature. Under OWA, making it equivalent could incorrectly classify complex valve assemblies that contain solenoid components but are not standard solenoid valves.

Disjointness Axioms
ManualValve
C1: ManualValve. Different actuation mechanisms are mutually exclusive - a valve cannot simultaneously be solenoid-actuated, manually-operated, pneumatically-actuated, and hydraulically-actuated.
Cross-Standard Observations
All three sources (ISO 15926, CFIHOS, POSC Caesar) consistently define solenoid valve as a valve with solenoid for quick operation and linear action. ISO 15926 additionally notes it as both an ACTUATED VALVE and ELECTRICAL ELEMENT, highlighting the dual nature. The definitions are remarkably consistent across standards.
