Calculation
Inlet pressure: Set the available pressure for the entire gas pipe network at the main shut-off valve.
System name: If there are several systems within a drawing it makes sense to name each MSV in the field in order to easier identify them in the calculation dialog and in the printouts.
Nominal diameter: The nominal diameter results either from the calculated dimension of the section part (entry = Section part) or it can be preset (e.g. DN20).
Connections
The connection type can be selected from the drop-down list or is set by the program in the Standard entry.
