This dialog is used to define a valve characteristic entry in the Valve Characteristics Engineering Library.

The dialog consists of a table containing the following attribute columns:

• Relative Closure: Percent opening of the valve (100% = fully closed, 0% = fully 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).

Click New to add a new row to the table. Click Delete to remove the currently highlighted row from the table. You can hold down the Ctrl key while clicking on items in the list to select multiple entries at once.
