Mulit-postioning with pnuematics this year?

I agree with ahecht here. It is only controlling what air we exhaust and what air we keep. We used this system all last year and we have never had any concern of safety or legality of the system. Looking on it after the facts presents it may occasionly run a few psi above 60. All the pneumatics are rated for 125 psi for these reasons. I honestly don't have any problem with anyone who runs this system at full capacity and occasionly has air go above 60 psi, only when you are extending the cyclinder. I take the word "working" air as the air coming from the regulator through the solenoids which is definitely 60 psi and not out the exhaust. The exhaust is not working rather it is being worked upon. If you route it through another solenoid to run another cyclinder then it is working and above 60psi and illegal. But these are just my view.

Good luck to anyone trying to do this. Also, generalbrando, would putting an air tank in series with the exhaust be useless because then you lose the capacity up the line in the 120psi section and limit your ability to move large loads farther? We are only allowed 2 air tanks. I guess you could just use a lot of the tubing and practically make a storage tank.
