Re: Solenoid question..
You can use yet another regulator to step down the pressure to say 30psi.
Then have a solenoid at the 60 psi level and another at the 30psi level.
Join one outlet from each solenoid in a T-fitting with the third tube going to the cylinder.
You'd only want one of the solenoids 2nd output port tubed to the retraction side, and the other solenoid's 2nd port blocked.
There are other methods as well, this is only one way.
