Pneumatic Valve Racks ¶

Our in-house pneumatic valve system uses Arduinos with solenoid driver shields to actuate small Clippard poppet valves mounted on fill/empty manifolds. The electronics are documented on Pneumatic Valve Drivers. This page describes the mounting arrangment for the manifolds.

The SolidWorks models is available as four-manifold-station.zip, or may be browsed as individual files in the four-manifold-station folder.

Four Manifold Card ¶

../_images/four-manifold-station.PNG — CAD rendering of a single manifold driver card. Each laser-cut 6mm plywood manifold card holds four fill/empty manifolds, eight valves, and one Arduino with driver shield.¶

Full Card Rack ¶

../_images/rack.PNG — CAD rendering of the large card rack which is CNC milled from MDF and can hold all four manifold cards to supply a total of 16 fill/empty output channels.¶

Two Card Rack ¶

../_images/two-card-unit.PNG — CAD rendering of a two-card rack which is laser-cut from 6 mm plywood and can hold two manifold cards to supply a total of 8 fill/empty output channels.¶
