Doubt if you will get a replacement for that, havent seen them for many years, you never know though someone might see it and have some, you will probably have to change the whole valve
you dont really need to drain the rads to swap the valves , do you know if your system is open vented or a sealed system ? tell us what make and model your boiler is and that will be a good indication
Even if someone had some in stock, the sensing vial will be guffed by now.
It's a Worcester Greenstar Ri. It's the kind of system with a header tank and a second tank in the loft and no pressure gauge.
I have a horrible suspicion the pipes are microbore as well. Need to measure properly though. House is mid-80s Wimpey.

Well, as long as you’ve no serious blockages, it certainly won’t hurt to give the system a drain down and flush through with some chemical and fresh water from the mains. Check your F&E tank and give it a clean out if it’s full of gunge before draining down then, once it’s clean, leave it running from the ball valve for 30 mins or so, whilst opening a path to drain. When refilling, add some kalchem which is a cleaner and inhibitor, and can be left in the system.
