Wolesley's page suggests a similar one is OK up to 20 bar. How does water pushing against the seal at 20 bar differ to gas pushing against the same seal?

The downside with the Screwfix one is that it needs a screwdriver to operate. The one originally proposed has tool-less operation so something of the same concept might be a better alternative (Screwfix 29086 and/or 21860 red handle cheaper than blue handle).

Try it and see?
The grease is one aspect, the design of the valve is the other, ball Vs taper
There is a reason we have gas and water valves, pressure isn't everything

I would guess that theres probably a lubricant in there that will either be washed away by a liquid or is just not something you want getting into water that someone may drink or wash in.

Isolating valves - they all leak when you come to turn them off. People love painting them too for some reason.
A lever ball valve would be much better than a gas tap. But fairly bulky and not aesthetically pleasing if on show.
The problem is if you don't operate them regularly they can still leak.

That's basically what the gas tap is.

Those are just awful on mains water, I can't begin to count the number of them I have seen the ****ty plastic handles just tear off if there's just a hint of scale or corrosion in the pipes...
Not what you want from an isolator, at least the screwdriver type operated type is reliable once you find a screwdriver.
I'm thoroughly in team "use a proper ¼-turn ball valve":

That’s something I make a point of doing at least once a year, along with the main water stop cock: fully close and open it several times, make sure it does actually close the water off.
I learned it working on ships, part of the planned maintenance system.

They are the same valve underneath as the screw ones, just with a plastic handle - ours has been there 8 years and hasn’t leaked, maybe I’m just lucky…

Have you operated the valve in those 8 years?
My daughters rental hovel had one of those handle types valves for the washing machine. When I tried to close off water to get the washing machine out the plastic handle just rotated over the square drive inside it, as the valve was seized open. Once the handle had fallen apart totally I managed to get a grip with pliers to turn it.
