Can a Radiator valve be used as cold water restrictor ?

[Darren1234]

New fridge freezer, needs plumbing in for the cold water drinks dispenser.

The supplied fitting to connect the filter to the water supply has a size and thread equal to a radiator valve (the other end is to connect to 6mm plastic pipe) .
Is there any reason I can't used this as my shut off valve for the mains water supply instead of a normal water shut off valve and then I would require a matching coupling of some sort.

It means the coupling and shut off would be housed in one unit effectively, but I'm wondering if anyone knows that radiator valves aren't set up to take the pressure of mains water?

Thanks
Darren.

this might be better and will take mains water.

Yeah, I know that's the right device but the supplied fitting for the filter has a huge thread on it , the same size as a radiator valve. If I use the above I still then have to get the up to the correct coupling size which then requires another piece.

Unless the above comes in a 15mm->Radiator size coupling ?

those valves come in 15mm to 3/4" as used on washing machines etc.
