How to remove this TRV?

[Rackers]

Can't seem to shift this thing and all the threads I've looked at seem to have different spec TRVs. Any ideas?

Thanks

Unscrew the knurled nut underneath and the head should lift off.

Thanks that did it. Pin appeared to be stuck and seems to be a bit stiff still! Rad is the only one is the system that is stone cold so fingers crossed it'll warm up at least a little!

Thanks

In the past I've freed TRV pins with a pair of pliers and a bit of up-and-down movement.
