Hello
Why does not ‘Isolation Valve’ locate ON pipe (like another elements) and can be moved over with a dotted line?

Please have a look at this support solution.

As for why the isolation valve is associated to the pipe (as indicated by the dotted line) and not connected to the pipe ends like other nodes: this prevents the need for extra pipes in the model. If you have a valve in the middle of a particular run of pipe, the isolation valve element is associated with that pipe, so you only need to have one pipe element in the model in this case. If you were to use one of the other valve types like a TCV to represent the isolation valve, it would "split" the pipe (since pipes need to be physically connected to other nodes like TCVs), causing there to be two pipe elements to model this case.
In a situation where you have a large system with a large number of isolation valves, adding them to the model (for use with the criticality tool for example) could result in a large increase in the number of pipes. This could have implications with licensing (staying within the pipe limit), model size/complexity and asset management (having to work with multiple pipes/labels instead of a single pipe - though our GIS-ID feature, if used, will ensure this is not a problem with GIS synchronization workflows.)
