More Valves

I've been doing quite a bit of parts with Shapeways lately both flow models and functional parts.   One of the latest is a rework of my servo actuated plug valve.


Two parts allow a Swage-Lok SS-4P4T valve to be actuated by a Hitec servo - I recommend a high torque metal gear model like the HS-7954SH.   The only other hardware required are (you'll need taps to clean up the threads in the nylon):

qty 4     8-32 x 5/16" Socket Head Cap Screws, McMaster-Carr 92196A191
qty 2     4-40 x 1.25" Socket Head Cap Screws, McMaster-Carr 92196A302

The printed parts are available on Shapeways
