Question: How do the various thayer/axial valve brands differ in terms of maintenance demands?

I assume that instrument innovations/infinity axials are relatively low maintenance because of the ball bearings. I also assume that first generation OE Thayer valves are relatively high maintenance because they are the first iteration (and most are 30+ yrs old by now). Where do Edwards Axials and Shires Axials fall on this spectrum?

I assume that they’re all higher maintenance than rotors, but I’m curious if (and how) they differ from one another in terms of maintenance demands.

Thanks!

Really no different than rotors!

Consistent oiling is the key!! And regular maintenance!

Valves, rotor or axial, really need 2 kinds of oil:

A thin, piston oil, like Al Cass or similar for inside the valve body-into the slide receiver.

And

A heavier oil for the bearings. Like what used to was Hetman 12/12,5/13

They're all about the same, just worn valves will have to be taken apart and cleaned more often. Older valves are usually more worn.

Thank you! This was helpful.
