ِAvailable Valve Data

While trying to insert a 1500 # check valve on the piping input screen using the valve flange icon, I got the following message:
"No data dase value"
Does this mean that I've problem or no data is available?

This simply means that for the size and pressure rating you selected, there is no data in the database. You will have to look up this data and enter it manually into the input.
