I also thought Sunvic, but I couldn't find that identical type.
Why not just replace the valves with a different, but similar brand if they have same connections?

Will the new heads not fit on old body

Thermostatic Radiator Valves

Unfortunately not new heads are m30 x 1.5. I think the old one's are m28 x 1, so I might have to buy adapters or drain down and change the valve body as well

Take it down to a good plumbing merchants and I am sure they can find something for you.

For the time you will waste running around just replace the complete valve.

Even if a new head fits, if it's not identical, you may find that the temperature settings are far out. I've seen heads, when put on the wrong bodies, give a reasonable temperature when set somewhere between 0 and 1.
