Re: Two pressures?

There is a way to retract the cylinder using no air at all - leave the other end of the cylinder open - no connection, and use a small spring or the surgical tubing to retract the cylinder

then you only need a single valve to pressurize the business end, and when you close the valve it will vent the air, and the surgical tubing will retract the cylinder.
