Hello! I need to fit a Honeywell Evohome TRV to this valve.
Hard to tell but I think the diameter of the threaded area is 28mm. There is, I would say, 1mm between each thread. The height of the pin itself is 13mm. The height of the top of the pin from the top of the thread is about 20mm.
Once I know what standard this is I can buy an adapter. If it's non standard I have to fit a whole new valve which I really hope to avoid.
