Re: Mechanical Regulator Movement?
We have in the past used multiple valves and pulsing them on and off through fancy code to achieve different speed, direction, and position of a pneumatic cylinder, including stopping a cylinder in mid-travel. You have to be a bit careful of the mechanical abilities of the valves if you plan to do this (we had one valve start producing metal shavings from being switched faster than it was rated for).
EDIT: you could also have a system where you have a cylinder A. it is connected, through two T fittings, to TWO valves, B and C. B is downstream of a regulator to 30psi. C is downstream of a regulator to 60psi. (You have to account for the return air here too somewhere.) Switch one valve, you get 30psi at the cylinder, switch the other, you get 60psi.
Another alternative is your motor-driven regulator concept, only you apply it to a flow-control fitting.
