Valve Operation dialog
You can use this dialog to analyse the operation of a valve, including viewing
its behaviour during a simulation.
The dialog can be displayed in one of the following ways:
- On theControl Data Summary view, by right-clicking a row in the valves grid and choosing
.
- On the Valve grid view
of the Links grid,
by right-clicking a row and choosing .
- On the Valve
property sheet, by opening the Valve Parameters page and clicking the Valve Operation button.

Option |
Definition for non-simulation results |
Definition for simulation results |
Max Flow |
Maximum Headloss
axis value is set to show headloss at maximum flow at the current valve
percentage opening. The Headloss axis range does not change as valve percentage
opening is changed. |
Flow axis range
is set by min and max flow values. Headloss axis range is set to show
headloss at maximum flow at current valve percentage opening. The Headloss
axis range does not change as valve percentage opening varies. |
Max Flow and Opening |
Maximum Headloss axis value is set to show headloss at maximum flow. The
range is adjusted with change in valve percentage opening. |
Flow axis minimum value is set by min flow value. Both Flow and Headloss
axes maximum values are adjusted with change in valve percentage opening. |
Fixed value |
Maximum
Headloss axis value is set at the value specified in the accompanying box. |
Flow axis
range is set by min and max flow values. Headloss axis range is set at
fixed value. |
|
Linear Scale in Graph / Log Scale in Graph
|
Changes between
log and linear scale on the graph. |
Opening (slider) |
Available only when the Simulation Results box is unchecked.
Allows you to change the percentage opening of the valve.
|
Min Flow |
For entering the minimum flow value. |
Max Flow |
For entering the maximum flow value. |
Layout (button) |
Changes the layout of the dialog and graph. Several layouts are available by clicking the button repeatedly. |
Simulation replay options and controls |
Additional options are added to the dialog if you open the report for
a valve in a completed simulation:
Simulation Results |
If checked, displays the current operating point for the valve.
|
Operating Points |
If checked, displays all the operating points for the valve during the simulation.
|
Iteration delay |
Because
the dialog only replays data for the valve, instead of the whole network,
replay at full speed is too quick for realistic analysis. You can use this slide
control to set a sensible delay that allows you to see the behaviour clearly.
|
Replay Control Buttons |
You can control the replay of the valve results in exactly
the same way as for the main simulation replay.
|
Parameters Grid |
Shows
important values at the current timestep, along with minimum, maximum
and average values.
