So what is the difference between mounting them on the cylinder exhaust and mounting them on the valve exhaust ? They're in the same leg of the circuit. and have the same direction of flow through the valve.
And they seem quite similar to last year's. and you cannot blow (ie at less than 2- 3 psi)either way. The checkvalve action you described (closed in the direction of flow control, open in the opposite direction) ought, IMO, to introduce no great amount of back pressure; yet I was able to operate the demo board (see above) at 30 psi with my circuit.
I don't need to worry about pressurized tubing being stiff, but I do worry about losing a piston when a vandal breaks the flow control off in an exposed position.
Anyway, we're both close to having the circuits on our machines ready to test the ACTUAL operation of the valves under higher operating pressures.
