Nicely done.

I have a possible problem.

I believe that the piston will not be as stiff in the
direction that the double solenoid valve is open
because the regulator will allow the pressure to bleed
off in this direction, but the plugged exit valve will
allow the pressure to get higher, thus allowing the
piston to be stiffer in this direction.

By the way, this is all just theorizing on my part, I
have not actually tried the idea.

Would this fix it?

Put a check valve on the input to the upper vavle (the
one marked "from compressor" in Shawn's Drawing.

What do you pneumatics folks think?
