These did not fit my ẹp radiator valves. If they fit your valves I am sure they would be fine, but to be honest it’s best to try and get the correct one from the valve manufacturer.

Quick delivery Works as described

I have two valves with broken heads. I used the diagram with the dimensions to check this would fit and one of my valves had a pin length of 6mm as per the diagram and my other valve had a pin length of 10mm.I tried the head on both valves and it doesn't work on either.You can see in other reviewers pictures there is a large spacer between the dial and the nut which is not in the product pictures. The only advantage to this spacer is it has slits in it so you can see if/when the dial makes contact with the pin.With 6mm pin valve the head only just touches the pin when set to zero (it is meant to touch the pin at maximum setting so you can close it down by lowering the pin).With the 10mm pin valve it touches the pin when the dial is between 2-3 so using standard TRV temp ranges i would guess setting the head to zero sets the valve to around 20c thus you can't turn the radiator off.

I question if these are in fact thermostatic, after fitting l find it to operate as a constant on or off no matter what number you have it too. However l would accept at this price you can’t really moan.Fitting was easy, they look great, not cheap looking, not a bad quality feel to them.
