Solenoid Question - 3 Position Cylinder

[Chris Fultz]

We may use a 3 position Bimba cylinder this year.

Has anyone used one? If so, how did you plumb it to get the two different actuations? What solenoids did you use? This is for an actual 3 position cycliner, not the set-up that used the magnetic switches to sense position.

The image below is from the Bimba catalog (http://www.bimba.com/pdf/catalogs/TRD_3P_Series.pdf). Basically you use 3 'valves' - one for each of the 3 ports. You can use two standard valves for this, one valve output is capped.
