We have always designed to minimise the tubing between the valve and the cylinder, as air in tubes between them is dumped when the valve is cycled, ie. the air in the tubes don't contribute to the force, but is still used up. Is this correct? Or am I being over-conservative in the volume wasted?

We'd like to avoid mixing inventories, if there are no 12v solenoids to plug into the 24v breakout, then it can't happen.

My favourite option, however Mech doesn't agree.

We are using 5/2 solenoids, (specifically these
