    There isn't much to it actually. Estimate the weight of the z-axis and then find an aircylinder that can deliver the force required to hold that weight. Make sure you do the calculations for a lower pressure than what you have, so i'm going to run 8 or 10 bar in my shop, so i designed the counterweightsystem to run at 5-6 bar, this gives me the option to increase the pressure if the z-axis is heaver than estimated...
    What about other system components like valves, regulators etc.?

    Well, a pressure regulator can be bought in almost all major "home depot"-like stores. So my plan was just to get one of those...didn't do much thinking on those parts....fittings etc will also be needed...but i'll cross that bridge when i get there :-)

    I assume he's running a manual regulator, but you could also use a controlled valve. Since he has an accumulator he's made a 'constant force' gas spring system. The accumulator will add enough capacity that he could use even slow-ish binary control on a valve and not need a proportional valve at all, as long as the valves have enough restriction (ie, small!).
