To be able to use components (such as valves / fittings) in planning systems (e.g.: Revit) accordingly it is required to set specific properties in the Revit classification.
For this first the adequate Revit Family Template has to be set:
Start PARTproject and in the directory structure, go to the part where the adequate class shall be assigned.
Open the tabbed page Classification and there, the tabbed page Revit.
Select the class. (In above figure (Metric) Door has been selected exemplarily.)
Listing of all currently available Revit family templates (*.rft):
Each template of the Revit classification has its specific attributes.
Most templates in Revit or classes in PARTsolutions have the following 5 attributes in the Revit classification. Values for width and height, for example, can be added.
Family category: The family category defines which class/category a part will have in Revit.
Family work plane based: ... defines, that the object can be placed by using the 3 default planes
Family always vertical: ... defines if an object shall always be placed "vertically".
This property sets the functionality of the component e.g. when being used in a piping specification. There are pre-defined values, which are set according to the correct "Family category" (the category is described in brackets).
In the list field, set the desired value.
For the MEP[10]-field, mainly the following two values are used:
Example: With valves that shall break a pipe in two sections and connect with the pipe, the recommendation is to use Valve breaks into part type (Pipe Accessory).
A detailed reference (which part type creates which function) is available on the Autodesk help-site:

Revit family templates (*.rft) with corresponding attributes :
Details on this can be found under Section 3.5.4.2.1.1, “Revit: Load IES files in RFA (lighting fixtures)”.
For doors width and height attributes define the shell dimension.
Wall thickness – incl. plaster (as the door frame cannot react to the wall-thickness)
Wall opening width and height (must be wider and higher than the door leaf width/height because of mounting spaces) Common values for added spacing are: +35mm width and +17.5mm height. These values must be worked out and finalized with the manufacturer in the project workshop.
For windows width and height attributes define the shell dimension.
