I'm servicing a Honeywell zone valve on a hot water heating system. I need to re-grease some brass gears that are part of the valve assembly. The heating system operates at 140 F, and the valve has a little motor inside it, so the grease will need to withstand some heat. But the valve doesn't operate very often so protecting the gears from wear isn't very important.
Can anyone recommend a grease for this application?
