Default Air Dryer Purge Valve

My purge valve on the air dryer purges at 120 (so far so good) then continues to spew out some air until pressure falls to 90 lbs and then stops putting out air while the compressor is running. This is without using any brakes, either sitting still or driving. I had the dryer rebuilt. Still does the same thing. Cycles like this about every 2 or 3 minutes. I'm fairly certain this is not normal, but can someone give me some insight?

1997 Gulf Stream Sun Voyager 34' air brakes, air ride suspension. Thanks!

Found out the air dryer had not been serviced after all. Paid for it, but it wasn't done. Can plainly see that the lower kit parts were never removed. Will have to go back to the shop and inquire! Hmmmmmm! Bought a new dryer because I thought the kit had been done and hadn't worked. I'll be better off anyway with a complete dryer because it is all new and the upper is new also and with the desiccant filter. Purchased a new governor also.
