About 8 years ago, I installed a new OEM heater valve. It leaked from "day one".
Just recently, installed same type of valve. No issues so far.

There was discussion on this list about a run of new OEM valves that
were flawed.
If I recall, one could even test them by blocking the outlet and
blowing air through them.
Maybe it's taking a long time for vendors to sell off that stock?

I may eat my words, but it's possible the new valve I recently
installed may last some time.
