    Valves

    Hi

    How I can graphically see the valves in my Infowater model?. I have a number of PRVs in my model, but I cannot see them graphically. Thanks

    Badam,

    It's difficult to know exactly what you are asking here without more information or without looking at the actual model. We can't currently verify if you have an active InfoCare account based on your account information, but if you need further assistance and have an active InfoCare account you can email us at support@innovyze.com for more personal assistance. Oftentimes a phone call or WebEx can resolve your issue much more quickly than email or in the user forum.

    However, for the purposes of the other users on the forum here are a few suggestions. These will be presented in InfoWater, but would be slightly different if using InfoWater SA as the location of elements in the toolbars are different.

    1) Can you currently see your valve layer? You should have in your Table of contents a "valve" layer. Make sure this layer is checked on or you would not be able to see any valves in your model. If it is unchecked the valves will not get drawn.

    2) Can you confirm you have valves in your model? Please open the DB Editor (Database editor) and look at the Valve hydraulic table using the entire table as the scope. Make sure you have 1 or more valves showing in this table and that they are defined as Pressure Reducing type valves.

    3) Are you in a scenario that is causing one or more valves to not appear? Try switching the to BASE scenario in your model which will have all elements active. If the valves appear you should review the Facility tab settings for the given scenario as that is causing the elements not to appear correctly.

    4) If it is not one of the previous options, you may want to check to see if you have an issue with your MAP layer that is causing the valves not to draw. We would recommend saving the model before this next step so that if anything goes wrong you can always close the model without saving and revert to where the model was before this step. Under the InfoWater Menu-> Utilities-> Update Map from DB, select Force all Network option. This will redraw the Map file (what you see onscreen) according to what the DB has in it. If any valve elements were not showing up properly in the Map this would make the elements get drawn using the coordinate data stored in the model database.

    5) Lastly all valves by default will use a single color coding for all model valves. This is one of the reasons many modelers prefer to model normally open valves as junctions rather than as valves as it can be difficult to identify valves that really do something. See below for options of how you could make your PRV's easier to see.

    Option 1: Createa query that will identify Valves set up as PRV's. If you create a Valve Query with the following entry (VALVEHYD->TYPE=0) in will select all PRV valves in the model, If you have only these elements in the domain you can export these to a shapefile and add this back in to the model and use a specific symbol different than the valve layer to display them so they stand out more clearly. This will put a "Halo" around each valve that is a PRV and make it easier to identify these in the model. Here is an example:
    (click if need larger image)
    valve -PRV Halo.jpg

    This is generally by far one of the easiest ways to do this. This will make the valves that are PRV's clearly stand out from the TCV's used for normally open valves.

    Option 2:

    Create a layer file to display each valve type using a specific color coding.To do this do the following

    a) Join All layer tables using the InfoWater menu - Utilities -> Database -> and select Join All Layer tables
    b) Right click on the valve layer and select "Properties"
    c) Create a layer symbology for each valve type. Note you will ahve to manually change the labels used:
    (example- click if need larger image)
    Valve- Layer File.jpg

    While, you may wish to export all of your model valves to a separate layer so that you can easily switch to this view, you can use the layer file to display your valves by the valve type. Once this is created, close the properties and right click on the layer in the table of contents and select Save as layer file to save these settings.

    The down side to this is you are constantly resetting the display because of changing and viewing the current "domain" that it is difficult to use this directly on a model layer. But you can export your entire model Layer to a shapefile and use it there so that you can check the layer on and off easily. To apply a layer file to a layer right click on the layer and select "properties". Then go to the Symbology tab and select "Import" and then Browse to the Layer file saved earlier.
    (click if need larger image)
    Layer file - Applying a layer file.jpg

    Both of these options can give you a lot of flexibility in seeing the PRV's easier. I would generally recommend Option 1 as the easier of the two.

    If you have further questions please reply to this post.

    Badam,

    PS: This link provides an easy way to convert normally open valves to junctions as well if so desired: https://forums.innovyze.com/threads/...s-to-Junctions. This can make it clearer to just see valves actually doing something.
