where can I find 3d models of valves, right now I need a 1.5 inch socket weld ball valve, stainless steel
may be a bit late by now, but,
the obvious answer being on a solidworks forum 3D Content Central;
Free 3D Models, Free CAD Models
but i don't find them very good for a lot of "industrial" valve types like you have mentioned. but generally the ones they have are very good and have configurations.
also try GrabCAD they have a HUGE range to choose from but are generally generic so may be tricky or impossible to open in solidworks. just make sure you download one that is compatible with SW. (IGES, STL, etc.)
also try the manufaturer of the valve you are using as it seems to be more common for them to put a 3d dumb solid on their website. the only issue is normally they need to be downloaded one at a time in the size you want at that time.
if you come across a 3" flanged ball valve, let me know! lol.
