The pressure regulator is set for being at 60 psi when it is completely screwed up, probably closed, When you unscrew the regulator it moves from allowing 60 psi to 0 psi when completely unscrewed open. If you unscrew the regulator you will have very little pressure working through the solenoids, You will still have the same amount of air to be pushed out the cyclinder and through the solenoid exhaust but it will do it slower because of the low psi coming from the regulator. You will want the regulator to be screwed in some if not all the way if you want to take advantage of 60 psi. This sound like a possible problem.

To be for sure, double acting solenoid works by taking air through it intake, center hole on three holed side, which should come from the regulator and being able to turn one side on (open) and the opposite sides exhaust open. So when the side that goes to the back of the cylinder is switches on to, it extends the cylinder and pushes the air on the opposite side of the cyclinder out the exhaust of the solenoid and to the atmosphere. Make sure this set-up is right.

Lastly, always be aware of leaks. I don't think this is the case but it can't hurt to double check. Use soap and water or fully charge the system, leave for 10 minutes and check to see if the psi is at the same level.

If you have any more questions just ask. Good luck.
