If we use extra valves on the exhaust side (the ones we dont normally put fittings on) couldnt you pressurize one side and have the cylinder go all the way out, then pressurize the other side, and have the cylinder goto the CENTER position?
if you had a position sensor, and you used the flow restrictors, couldnt you control the amount of air in each side (using more than one valve) to position it anywhere between the two extreems?
Anyone ever play around with this or try it?
any thoughts? seems like it would be perfect for controlling the position of an arm, infinitely variable.

The setup isn't ideal, but you can prolyl bootleg it to work. The cylinders are fince for this, and it is done all the time but not with this type of valve. You will also need some position feedback(I don't think the reed switches will work. They are probably not fast enough.). If you try what you describe above, i would be interested to hear the results.
