I recently replaced all of the under-chassis Norgren valves in our 98/99 Royale. The bus has always been garaged but lived in the south for the first 10 years of its life. I found all of the valves badly corroded and the O rings brittle. One of the front Norgrens had failed internally. Norgrens are a simple, all aluminum spool type valve with very little to go wrong. Corrosion and age however can be their downfall.

Thanks Jon, for your suggestions and warnings in reference to changing rubber dependent components around the 10 year mark. Preventative maintenance starts at home where it's a lot cheaper and more convenient to get done than on the road.

Greg, Norgrens can be overhauled but in my opinion its more trouble than its worth. I can't imagine you could do so without removing them from the coach. They can be purchased locally but the savings was minimal.
