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.
