Details on Technical Data for Pressure Reducers
Information on the technical data dialog for Pressure reducers.
In this dialog box, you specify the component data that will be used in the calculation. In addition, for manufacturer-neutral fittings, you can select the connection type for the component connections.
The pressure reducer or pressure closed-loop controller has two connection points each of which are connected to a pipe. Generally you will initially draw the pipeline and then add the component to the pipe. The pipeline will be interrupted automatically and the component is connected correctly directly to the pipeline.
You are here:
If a pressure reducer is only inserted into the hot or cold water partial network, the consumers connected downstream will be in different pressure zones. This can lead to significant temperature fluctuations at the faucets.
Name
In this field you can enter an individual name for the component. Clicking on 
restores the original name and overwrites the previous entry.
Output Pressure
At first the pressure reducer is calculated with the status uncontrolled, i.e. the reducer is completely opened and acts passively in the pipe network (without effects on the pipe network).
Switch to Pressure Specification and enter the output pressure that is supposed to adjust itself downstream of the pressure reducer.
Pressure Loss – Settings
In this dialog box you either set a fixed Zeta value for the pressure reducer or a fixed pressure loss in hPa. To that end, activate the respective radio button to the left of the edit field.
Settings
In case a pressure reducer has already been added in the armature preselection, the corresponding component data will be displayed here. You may also assign the desired valve by clicking the button Select ... in the component data dialog. If a valve has already been assigned, click the button Reset to reset this valve.
Nominal Diameter
The current nominal diameter of the valve. If you have selected a manufacturer valve, you can choose a dimension here, which will then be used to set the valve. The set nominal diameter will be used for the calculation. If you de-select the option free next to the drop-down list, a nominal diameter based on the calculation results is assigned. The newly assigned nominal diameter is displayed the next time the dialog is opened.
locked
Enabled: The nominal diameter of the valve is not adjusted in the calculation.
Disabled: If necessary the nominal diameter of the valve is adjusted during 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.
