EPANET special junction


I use EPANET and i would know what does this type of node means in an EPANET map ?


It looks like a valve, but it’s not.

Best regard.


If I just look at it from the picture, it is a valve, can you tell me its role in the water supply network? That will facilitate judgment

thats a valve, a valve is a link l(like a pipe or a pump), not a junction.
