norgren for tag lift

[drivfour]

Although I realize lifting tag is rare, I may need to do so to get more traction in snow. The airbags exhaust when engaging lift tag lever, but no air going to the lift chambers. The shafts have been cleaned and are free. Can anyone tell me the location of the norgren that sends pressure to these chambers. I tried to follow lines but are buried somewhere.

John mine is in the area above tag wheel on driver's side. Replaced with a Prevost supplied Burkett valve when we did the "Tag axle logic improvement kit" that prevents tag from dumping when AUX air bleeds off.

My Tag valve is in the same spot as Billy's and was the hardest to access of all my valves. Remove the tag and drive wheels on that side, and sit on some blocks to get you as high as possible.I also had to replace the airlines that went to this valve as they were very stiff and nearly impossible to work with.
