Tado TRV compatability

Hi all, I was wondering if it's possible to attach a TRV to this radiator:

Here's a couple of pictures of the valves close up.

I installed the TRVs around the rest of the house but can't see any obvious way to install this one. That said I am an absolute novice generally, so I may be missing something.

And these two are our bathroom rad valves. Same question...

PS I know we would still need to leave one without a TRV and with the valve open to act as the bypass.

Thanks in advance!

    The valves on the first radiator are standard 15mm x 1/2" valves, but you have a 15mm to 10mm push fit elbow on the bottom. You can purchase a standard right angle TRV to replace this valve. The metal insert that screws inside the radiator is called the tail. The new TRV will come with a tail but you won't need to use it, because the existing tail looks like it uses a compression fitting. You re-use the push fit elbow.

    The second radiator valve is a 15mm x 1/2" corner valve, but the tail has a 3/4" union fitting. You need to purchase a corner TRV and it should come with a similar 3/4" union fitting. If a tail needs to be replaced then it will require a radiator allen key to remove and replace the tail.
