Rated 2 out of 5 by from Poorly Built Product Installed 16 of these TRV's about 3 years ago and since then the Sensing Heads have fallen apart in 5 of these valves. I suspect the remaining valves will suffer the same fate. Fortunately you are able to buy replacement sensing heads but you have to wonder why the sensing heads are sold separately - they should never need replacing if they are designed and built to last. The other problem is that the colour scale on the sensing head is not UV resistant and fades if exposed to sunlight and becomes unreadable.

Rated 5 out of 5 by from Stylish look Valves look fantastic on my new modern looking radiator. The price does not reflect the how good the valves are. Would buy again if needed.

Rated 3 out of 5 by from Thread too short I bought this TRV/Lockshield set to replace a faulty TRV. The product looks good and feels robust. My only criticism is that the thread at the bottom of each valve, which connects on to the olive/nut on the existing vertical pipework, is very short. It was so short that when I put the new valve on top of the pipework, it didn't go down as far as the existing olive. The threaded nut behind the olive wouldn't even reach the thread on the TRV, so it couldn't be connected up. The only option was to buy an alternative valve from a different manufacturer (which I ended up doing), or to hacksaw off the olive and fit a new olive/nut. This is probably not a problem for most people, but if you want a quick hassle free replacement, this isn't the one for you. I looked at various TRV/lockshield sets from other manufacturers, and the threads were all much longer than this Drayton one.

Will this angled Drayton TRV4 & Lockshield be suitable for a single panel 1800 x 375 x 65 rad where the feeder pipes come through the wall at rear of rad?

Asked by: Gulliver
If the pipes come through the wall in line with the radiator inlet connections then you would need corner angled valves. ( If your Flow pipe is on the right as it comes through the wall you would need 2x corner left valve ( As theyare not bi directional ( They are FLOW directional ) and the opposite if the flow pipe was on the left as it comes through the wall.

Do i need to always replace the lockshield valve along with the trv or can i keep the old lockshield valve and replace only the trv

Asked by: banda
No you do not need to replace the lockshield you can just replace the TRV valve if that is your preference.
