4 Working with the master
Dialog for changing valve data
Area (1) normally displays the parameters that can be adjusted.
Adjust the name of the valve and the pipe volume as required.
In the case of valves for hydraulic balancing, the maximum opening angle and
the leakage rate can additionally be adjusted.
Precise setting of the pipe volume controlled by the valve allows the quick adjust-
ment of the leakage rate during hydraulic balancing. The pipe volume consists of
the content of the entire circulation line to which the valve is connected.
The following table shows the pipe volume per pipe length meter for standard
pipe diameters.
Button (2) closes the dialog without making any changes.
Button (3) saves the changes and closes the dialog.
Adjusting the leakage rate to values outside 10 to 15% means that the DVGW
standard W554 is not complied with!
