About analysing valve operation

You can analyse the operation of a valve, including viewing its behaviour during a simulation, using the Valve Operation dialog.

There are several options permanently available in the dialog that allow you to control the range of the valve operation graph axes.

The range of the Flow axis is defined by specifying "Min Flow" (default value = 0 ) and "Max Flow" (default value = 10).

If you open the report for a valve in a completed simulation, the default values for minimum flow and maximum flow are set from the minimum and maximum flow experienced through the valve during the simulation. The default "fixed value" is set from the maximum headloss experienced through the valve during the simulation. You can change these default values.

You can print the graph or view, copy the graph to the clipboard for use in another application, or export the graph data to a CSV file.
