What is the neatest/most attractive shut off valve ok for CH?

[WaterTight]

I know cheap ISO's are no good. I hear the Radmaster (may have name wrong) iso valve's are ok'ish but they only go between the rad and the valve rather than on the pipe and at least one Toolstatio review claims they leak like the regular ones.

Levers and gates are fine but bulky so no good.

Is there any small shut off valve that is actually rated for CH systems?

Yes I know best practise not to have any but there are unusual circumstances out there where good options become few. One example might be communal heating systems where a flat owner wants the ability to make changes to their CH circuit without waiting for communal drain downs or requiring freezing etc

Thanks

I use the Pegler tee ball valves. They are full bore, steam rated, but have a small butterfly head rather than a lever. You can get them in red and blue, so they look smart.

Is that small enogh?

Butterfly valves

I get butterfly valves from Williams

Proper ballofix vavles are ok from what Ive seen, not cheapo ones but the real ones with the allen key hole in the middle. Nice and neat

"Broen Ballofix" brand ones all seem to have a slot for a screwdriver, not an Allen key, with a small female thread that will also accept a handle.

Looking at the manufacturer's handbook, the compact ones do not appear to be quite full bore, but neither do they appear restrictive. Certainly more compact that a butterfly/tee ball valve. The fact that they make them for radiators too would suggest they are all suited to heating application as I doubt the materials differ significantly. The full bore ones are bulkier.

Have you seen them in the flesh? I've seen them already installed in Sweden, but not seen the internals.

Im pretty sure they all have a hex hole in the slot to take an allen key, it may just be specific ones though. Ive seen loads in commercial buildings on heating circuits as well hot normal hot and cold circuits, never seen one leak. I think a 15mm valve reduces the bore size to around 10mm, but a radiator valve reduces it even more anyway so might not be an issue? Are you planning to fit them supply side of the radiator valve?

These are for rads and have hex holes in the slot

That's not a hex. It's a slot with a point in the middle where you can attach a handle on a blurry photo. Zoom in on the line drawing and you'll see what I mean.
