Once the doors are up, the only line failure that can make them fall is the
one from the ram to the solenoids. You could drain the air tank with the
doors up and they will not fall because the solenoids are closed, separating
the pressurized ram from the rest of the air system. So putting a check
valve in front of your oiler will not achieve the results you desire.
Moreover, you don't want to put a check valve in the line to the ram because
the air needs to flow both directions in that line, one direction to raise
the door and one to lower it.

Subject: Re: air door leak
Rod I have been dealing with a similar problem this past week. What I
thought was a leaking compressor turned out to be a worn out
compressor.
It won't pump up past 60 psi. Anyway before I knew I had a worn out
compressor I purchased an SMC AK2000-02 check valve
http://www.flo-products.com/floprod/smcval2ak.html I installed the
check
value immediately after the compressor.
I also purchased a second check value and am thinking of installing it
in
front of the oiler. The idea being if anything happens to the air supply
(blown line) when the doors are up, they will stay up.
Any thoughts or comments?
