SuperB Posted February 20 Share Posted February 20 (edited) Just wondering if anyone would happen to have any experience with the Sealco automatic drain valves that were on some B61's? Mine came with one, but it's long gone. My questions are which of the 2 air tanks would it have been installed on, and how/where was it mounted? Mine is a tandem axle tractor if that matters. Thanks in advance Edited February 21 by SuperB Quote Link to comment https://www.bigmacktrucks.com/topic/73884-b-model-automatic-drain-valve/ Share on other sites More sharing options...
Geoff Weeks Posted February 23 Share Posted February 23 Wet tank 1st after the compressor is where most of the moisture will be found. You could put them on all, but shouldn't need too. Air driers replaced the need for them. Quote Link to comment https://www.bigmacktrucks.com/topic/73884-b-model-automatic-drain-valve/#findComment-547022 Share on other sites More sharing options...
SuperB Posted February 23 Author Share Posted February 23 Thanks Geoff. That makes sense. It looks like there's an installation option on the Sealco instructions that shows the valve installed level with the tank, not below it. It shows the tubing coming off the bottom of the tank and going uphill to the top of the valve. The pressure should force everything up the tubing I guess. I can't imagine the valve was installed on the bottom of that rear tank (the wet tank), it seems like it would be pretty low, but I'm not sure. I just don't see where it was originally mounted, so I'll have to come up with something that works using that rear tank.
