Drayton TRV4 Classic Thermostatic Radiator Valve Integral Head

I haven’t had time to install the Drayton TRV4 valves yet but they are first class and I have no worries. Great price.

Competitive price, simple online purchase, messaged as ready for collection, within minutes from a local store nearby with easy parking.

This is a well made quality product, pleasing to the eye compared with other bulky similar valves. Quick and simple to fit.

Good valves only change due to age, simple and easy to exchange

Not cheap, but only brand i trust. Hopefully this one will outlast previous.

Moderising my TRVs as a replace older radiators and valves. This is my 3rd Drayton valve. Replaced because of their modern sleek design and reliability.

Replaced Altech TRV which are not as reliable or long lasting as these.

Replacement for existing thermostat which failed after 20 years.

Nice looking valve head but not robust and prone to thermal degradation leading to failure

Used many of these, perfect item and the top part can be replaced separately- they all degrade after years of use

Good quality valves but not alot of room in the valve body if replacing different valves so may need to replace existing tails nuts and olives which is good practice anyway.

I bought X4 of these TRV4's to replace some of the original valve heads on my Gas CH system .The original heads started to fail one by one after 7 years in service.
The common failure mode in my batch being the rotating part of the body comes loose and the temperature control head just falls apart. The chromed metal top appears to be a friction fit on the composite body. I think the continual temperature changes may cause the composite to degrade and metal top to stretch due to different coefficients of expansion .

Perfect product, good price, very easy to replace, just screws on.

Perfect replacement at a fair price - easy to order online - ready for collection within one hour

These are nice looking valves, some seem to be large and "clunky" looking but importantly the quality is superb

Perfect replacement for broken TRV4, supplied promptly after bank holiday weekend.

Excellent radiator valve does exactly what you would expect it to at a very reasonable price

Successful replacement for existing unit that had become very stiff to operate (but that was after 20 years or so!). Very easy to install without need for any tools.

Found this completive priced replacement item on line. Local shop was very help full & easy to deal with.

Product is fine. Don’t rely on parcel force next day delivery as they don’t deliver next day.
