Re: How to use multi-positioning?
couldn't you use a needle valve with a servo to control the flow rate and their for control the length but limiting air going to it

Re: How to use multi-positioning?
As I said last year, 2 double acting solenoids, one to control the actual piston throw, make that solenoid's exaust common, as in put fittings on the EA and EB ports, T them together, then put it through a pilot controled check valve. On solenoid 2, plug either port A or B, and then control the check valve with the solenoid. It works in the most brilliant way. I've done it, and it works great. Either that, instead of staging a piston like this, just find where you want to stop the piston in mid throw, and get 2 pistons that equal the total throw you want, with one the place where you wish to stop, the other is the whole stroke.

Granted you could hack the servo...or gear it up...but you would probably lose the high resolution that I'm guessing the was the draw to using a servo in the first place... Hope this helps -Bill |
