Steve,
The function of the valve would be to close when the compressor starts up to refresh, then open the valve when the compressor has refreshed it would shut off. So it would could be wired to the compressors motor, I guess. It allows the compressor to recharge the compressor air tank without the additional load needed to drive the booster and furnish it with air. Also if one of the compressors shutoff pressure is higher or lower it would not affect the recharging compressor.
I have done this manually before and it made a difference in how long the Cats had to run, and of course if they run less, say 20/80 as opposed to 30/70, you produce less heat and in turn less wear and tear not to mention water.
It appears that the isolation valve on the Maddogstocks site is a manual valve. I have a manual valve on each of the 3 compressors that I used to see if my concept of a automatic valve actuated by the compressor coming on to refresh. I suspect a servo could be used, however I am ignorant of such things.
Thanks for the tip Steve.
RC
