The grid form for valves includes all valves (for pressure
regulation) in the model. Here, you have a direct overview of how the valves are
set in the model.
In the map screen, the pipe in which the valve is located
is highlighted when you highlight the valve in the grid form. If you
double-click in the row number column, the detailed form for the highlighted
valve is opened.
To create a new valve, right-click in the grid form and select Create new.
This opens a detailed form where you define the function of the valve.
Give
the valve a name or select an existing valve from the list at the top
right. This valve has a type linked to it (V100) and an opening degree
(15° from closed) is set. The reference value type must therefore be set to
no setpoints . The valve is located in pipe A1215 in the return
pipe adjacent to node F995, and therefore the field for fixed pressure reduction
in supply pipe is empty, and for the supply pipe the fixed pressure reduction is
set to 0 (kPa). When a fixed pressure reduction or an opening degree has been
entered, you cannot use a reference value. In the same way as for pump (see
above), the icons adjacent to pipe name and node name can help you to position
the valve in the model. The values which you enter for a valve relate only
to the current model. Thus the same valve can be used in several models with
different settings! See also the section Pressure regulations – pumps and
valves.
