IfcValveType: public Ifc4::IfcFlowControllerType¶
The flow controller type IfcValveType defines commonly shared information for occurrences of valves. The set of shared information may include:
common properties with shared property sets common representations of shape common materials common composition of elements common ports applicable assignment of process types
It is used to define a valve specification (i.e. the specific product information, that is common to all occurrences of that product type). Valve types may be exchanged without being already assigned to occurrences. Occurrences of IfcValveType are represented by instances of IfcValve.
HISTORY: New entity in IFC2x2
Property Set Use Definition The property sets relating to this entity are defined by IfcPropertySet and attached by the HasPropertySets attribute. Refer to the documentation at the supertype IfcFlowControllerType and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: Pset_ValveTypeCommon
The following property set definitions are applicable to this entity according to the PredefinedType attribute:
Pset_ValveTypeAirRelease (AIRRELEASE) Pset_ValveTypeDrawOffCock (DRAWOFFCOCK) Pset_ValveTypeFaucet (FAUCET) Pset_ValveTypeFlushing (FLUSHING) Pset_ValveTypeGasTap (GASTAP) Pset_ValveTypeIsolating (ISOLATING) Pset_ValveTypeMixing (MIXING) Pset_ValveTypePressureReducing (PRESSUREREDUCING) Pset_ValveTypePressureRelief (PRESSURERELIEF)
Material Use Definition The material of the IfcValveType is defined by IfcMaterialConstituentSet or as a fallback by IfcMaterial, and attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship. It is accessible by the HasAssociations inverse attribute. The following keywords for IfcMaterialConstituentSet.MaterialConstituents[n].Name shall be used:
‘Body’: The primary material from which the object is constructed. ‘Operation’: Material from which the operating mechanism (gate, globe, plug, needle, clack etc.) of the valve is constructed.
Port Use Definition The distribution ports relating to the IfcValveType type are defined by IfcDistributionPort and attached by the IfcRelConnectsPortToElement relationship. Ports are reflected at occurrences of this type using the IfcRelDefinesByObject relationship. Refer to the documentation at IfcValve for standard port definitions.
