Pushing on both sides of the piston...

When I played with an air cylinder an the regulator the
other day, it was very easy to push on the piston and
make the regulator bleed off the excess pressure.

Also, in your analysis, you are forgetting that you
have put 60psi on BOTH sides of the cylinder piston.
When you net out the forces, I believe you will find
that the piston will act like a spring is holding it in
place. The higher the pressure, the stiffer the spring
but it still acts like a spring (remember PV=NRT from
physics and/or chem class?).
