Details on Component Data for Shut-Off Valves
Information about the technical data dialog for shut-off valves.
In this dialog, 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 possibility to select special manufacturer components is not available in all versions of the program. Which manufacturers and components are available also depends on the installed product data sets.
You are here:
Name
In this field you can enter an individual name for the component. Clicking on 
restores the original name and overwrites the previous entry.
Design Data
This section displays the calculated values for the Mass Flow Rate, the Design Mass Flow Rate, and the Design Nominal Diameter.
Valve Data
Select ...: Opens the dialog Select Valve Series for selection of manufacturer-specific and user-defined shut-off valves. The range of manufacturer valves depends on the installed manufacturer datasets. Further valves can be imported via the VDI 3805 interface in the Select Valve Series dialog.
Reset: The Reset button resets the manually assigned armature to a neutral model.
Info …: Available when valve data is selected. When using manufacturer-specific valves, opens the dialog Information about this Valve with further values and information stored in the data set. For custom valves, the Curve Data dialog opens with information on the custom data set.
Nominal Diameter
The current nominal diameter of the valve. If you have selected a manufacturer-defined valve or a user-defined valve, you can select a dimension here to which the component will then be locked. 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.
Zeta, activated:
Enables the specification of an additional pressure loss in the form of a zeta value.
kvs, activated:
Specifies the flow coefficient of the valve in opened state.
: Opens the kv Value from Pressure Loss dialog, where you can calculate the kv value by inputting the pressure loss and the volume flow.
Pressure Loss Valve
Shows the pressure loss of the valve in the current discipline.
