#### 7.3.3.14 IfcValveType

| Type de vanne
| Ventil - Typ

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
- common materials
- common composition of elements
- common ports

It is used to define a valve type specification indicating the specific product information that is common to all occurrences of that product type. The IfcValveType may be declared within IfcProject or IfcProjectLibrary using IfcRelDeclares and may be exchanged with or without occurrences of the type. Occurrences of IfcValveType are represented by instances of IfcValve. Refer to the documentation at IfcValve for supported property sets, materials, composition, and ports.
