Two plastic ball valves for use with plastic or metal hoses.
Some parts of the objects have turbosmooth modifier, which can raise the resolution for softer edges though no more than 2 iterations are needed.
The materials used are Arch&Design, without texture maps.
Turning the handles rotate the ball valve inside, for detailed shots if needed.
3DS Max 2010 , FBX and OBJ versions are supplied in the supporting items downloads.
