Two norgren valves in steering compt
on a Liberty serve what purpose? Photo attached. Probably been discussed a bezillion times but…
One is leaking auxiliary air from an unused port on the bottom. I’m asking because if these are part of the “auto level” system which I never use, I may want to simply eliminate them if that’s possible.

Yes, Liberty added them for their auto level system.
The Norgren part# for them is K41EA00KS1KV2.
Norgren sells them for $115 each
or check ebay

That’s what I thought. Never use auto-level. Can I get rid of them?
What will happen if I remove them and cap air lines? Theoretically, if I had a Liberty pneumatic diagram, could I disconnect air lines at the source?
-
If you get rid of them you have no means of discharging air in the rear air bags if needed to level the coach.
They open to bleed air from the left or right air bags using the Liberty switches for the left and right rear.

I’ll bet that’s why I’ve been having so much trouble finding my RR suspension leak!
Any reasonably easy way to convert back to original from Prevost?
-
Joel, you can switch it back but there is nothing wrong with the system as Liberty modified it.
I don’t use the automatic leveling either, but there is no way I would revert back to the original Level Low. You would be changing the LH control panel to eliminate the Liberty controls and replacing them with Prevost controls and you would be rewiring the system to revert back to a single 3 port Norgren that is the exhaust valve for all three systems.
I forgot earlier, but Don’s numbers may be good, but since he has a Classic they might be 12V. I can’t remember if it is only the center solenoid valve in the manifold that is changed to 12V or if the valves being discussed are 12 also.

Thanks, mine is actually labeled K41EA00 with no suffix letters/numbers. I have a couple photos from one for sale on ebay to compare.

yes, the coils on my auto leveling Norgrens are 12v, but can be changed to 24v and will operate perfectly. New from Norgren, I’m not sure if this valve comes with a 12v, 24v, or no coil at all. Call Norgren.
I don’t use my auto level either. -
I thought only the ride height coil was 12v and the rest 24v for a Classic.
-
All auto level are 12V and the center (road mode) is 24V on this XL Classic.

Tom, this is proof we may not remember things as well as we used to. That is why I expressed how I wasn’t sure.
I like to think my brain has so much knowledge, that as more is added some has to be sent to the trash but we both know that ain’t true.

This discussion is about auto level Norgrens on the floor of the steer compartment, it’s not about the 5 stack.
-
Don, I know that and hope if anyone is replacing those valves they get the correct voltage for the operating solenoids.
-
Yes Jon, but Tom and Chip I believe are talking about the 5 stack.
-
Tom we know is struggling with senility. I try to help him, but at his age it might be a losing battle.

Sheesh, I’m going back to sleep.
