Huh. We have really hard water here (17° dH = 3 mmol/l = 303 ppm) and I never heard of any recommending that or having issues with that. Maybe German valves are just built to work in such hard water, as that’s really common?
Huh, wonder if it’s something about hot water? I wish I had a hot water valve, but what I have is a geyser and a durchlauferhitzer and the electricity costs that come with them :/
We have the same problem in Australia. I remember a plumber looking at a shut-off valve and saying that no-one had turned it off in 20 years so it's going to be hard to turn, and will start to leak after we do turn it off.
Newer types have way better longevity so you don't really need to exercise them.

the two warm-water-valves in my mietwohnung are stuck.
they recently wanted to replace the zähler, but couldn't, because they couldn't stop the water.
now they're going to send some special guy. well, at least that's what they said a few months ago 🤔
