Details on Technical Data for Flow Dividers
Information about the technical data dialog for flow dividers.
In this dialog, you specify the component data that will be used in the calculation. In addition, when selecting Manufacturer Product - VDI 3805, you can choose the connection type for the component terminals.
The flow divider prevents, in combination with a ring main, the stagnation of the water within this ring main.
For the calculation it does not matter in which direction the flow divider is inserted. For a graphically correct presentation the symbol is inserted in flow direction in the ascending pipe. At the top end of the flow divider a circular pipe closure (with layer ring main) is drawn, at the bottom end of the flow divider a potable water pipe (cold or hot water pipe) is created. The faucets are connected to the circular pipe closure and to the potable water pipe.
If water is tapped above the flow divider, this will cause a negative pressure in the constricted part of the component. This will cause a differential pressure above the ring main. Thus a hygienic flow within the ring main is generated.
The flow direction for the calculation is determined by the ring main closure.

This is the standard setting for the flow divider. If no manufacturer product is selected, a corresponding error message is output in the calculation.
Select ...: Opens the dialog Select Valve Series in which you can select a manufacturer-specific flow divider. The selected flow divider and its properties are included in the calculation.
Reset: Resets the selection of a manufacturer-specific flow divider.
Info …: For manufacturer components, this opens the corresponding fitting information dialog, which displays the characteristic curve diagram and additional information about the manufacturer component, depending on the dimension.
Nominal Diameter/fix: Drop-down list with the available nominal diameters of the selected flow divider. Once a dimension is selected, the option fixed is enabled. The selected dimension is then used for the calculation.
Inlet, Outlet
Drop-down lists for selecting the connection types for the component's connections. This option is available only for manufacturer-neutral components. After selecting a connection, the selected connection type is also assigned to the other component connections. If necessary, you can also assign different connection types to the connections. The selected connections are included in the bill of materials. Based on the connection definition and the selected piping system, any required fittings will also be included in the bill of materials, provided that the data set for the selected piping system includes them.
Volume Flow Rate/Pressure Loss: Shows the calculated flow rate and pressure drop for the selected flow divider.
Show Flush Relevant Consumers: Depending on the selected product data, you can view the fixture relevant to the flow divider.
Valve from Product Data
Model Selection: Depending on the selected product data and the set pipe system, the assignment is carried out automatically. Figure 640 or 650 is automatically recognized as Manual and the stored values are accepted.
Zeta Value: The Zeta values are suggested by the program. Using a flow divider of a special manufacturer, these values are fixed, whereas Zeta values of neutral components can be adjusted.
kv-Value: If values have been stored for an automatically detected , they will be displayed here. If no values are available, they can be entered manually.
Reset: Resets all edited input fields back to default values.
Manual Entry
Model Selection: Displays the automatically identified model.
Zeta Values
Enabled: The pressure loss of the flow divider is determined based on the values for Branch Flow Separation and Flow Through.
kv-Value
Enabled: The pressure loss of the flow divider is determined based on the kv-value of the flow through. The Opening Pressure Loss is the minimum pressure loss of the component in the flow through.
Reset: Resets all edited input fields back to default values.
