Chattering Gas Valve

OK, this topic resurfaces occasionally, with limited clarity. Recently I have been contacted by several people who's boiler gas valves are chattering. It's not 60-cycle hum, it's valve chatter. Now some of these have apparently been submerged in recent basement flooding incidents. These are not usually big-time floods, but perhaps just enough to submerge the valve (these are all off the shelf Honeywell). Sometimes they seem to still work, but chatter. Now this makes me think voltage issue, and perhaps internal moisture is decreasing voltage across the coil, but that's sort of irrelevant. Replace or wait and hope for the best? Thoughts?

    If it's been submerged, whether a big time flood or a little time nuisance, it needs to be replaced. Period. Not an option.

    What @Jamie Hall said any controls or wiring under water need replacement. Not an option. Don't take on that liability
