Why does Valve Pressure rating drop-down listing only shows NS (Non-Standard) in an AutoPIPE model?
Per the screen shot below,
Left side of image: inserting a valve on an 8" pipe, Pressure rating was available in library for valve selected
Right side of image: inserting a valve on an 60" pipe. Note the Pressure Rating drop down listing has only NS available. When the valve library does not have any data available to populate a drop down listing only NS will be displayed. Therefore only option available is to select Pressure Rating = NS, and manually update information as needed. Otherwise, update valve library with additional information.
