Several years ago I downloaded a very nice assembly model of a brass ball valve from the old 3DCC. The file name was SW3dPub-Ball-Valve-DEFAULT-23561. It was a 1/2 inch NPT size and now I would like a similar model with 1/4 inch NPT, but I cannot find the original model or anything similar. 3DCC has a ball valve from Reid, but it is not very realistic. Any of you guys know where I might find a good model? And what happened to the old one?
