Pegler Thermostatic Radiator Valve Playing Up, any Idea how to fix?

[ansel82]

Hi,

We have Pegler TRVs installed and in one of the
rooms it seems to have stopped working.

When the heating is on the radiator remains
hot even when the valve is set to zero.

If anyone has an idea how we can fix this I would
really appreciate it because I would like to have a go
at repairing it

put a cloth round the TRV and give it a whack with some water pump pliers, if that doesnt work then head off the TRV and try and free the pin, if that doesnt work then by a new TRV
