Valve Characteristics Dialog Box

The following management controls are located above the valve characteristic list pane:

New	Creates a new valve characteristic definition.
Duplicate	Creates a copy of the currently highlighted valve characteristic definition.
Delete	Deletes the valve characteristic definition that is currently highlighted in the list pane. You can hold down the Ctrl key while clicking on items in the list to select multiple entries at once.
Rename	Renames the valve characteristic definition that is currently highlighted in the list pane.
Report	Opens a report of the data associated with the valve characteristic definition that is currently highlighted in the list pane.
Synchronization Options	Browses the Engineering Library, synchronizes to or from the library, imports from the library or exports to the library.

The tab section is used to define the settings for the minor loss that is currently highlighted in the valve characteristic list pane. The following controls are available:

Valve Characteristic Tab	This tab consists of input data fields that allow you to define the valve characteristic.
Relative Closure	The initial relative closure used at the start of a steady state or EPS run. (A relative closure of 0% means the valve is 0% closed, or 100% open. Conversely, a relative closure of 100% means the valve is 100% closed or 0 % open).
Relative Discharge Coefficient	The discharge coefficient of the valve relative to the fully open discharge coefficient. A Relative Discharge Coefficient of 100% represents a fully open valve (exactly equal to the fully open discharge coefficient) and 0% represents a discharge coefficient of zero (fully closed).
Library Tab	This tab displays information about the valve characteristic that is currently highlighted in the valve characteristic list pane. If the valve characteristic is derived from an engineering library, the synchronization details can be found here. If the valve characteristic was created manually for this hydraulic model, the synchronization details will display the message Orphan (local), indicating that the valve characteristic was not derived from a library entry.
Notes Tab	This tab contains a text field that is used to type descriptive notes that will be associated with the valve characteristic that is currently highlighted in the valve characteristic list pane.
