Drayton TRV4 valve problem

[minoan]

First, I am not a plumber, merely a house holder with a problem.

I have a house with central heating radiators, all of which are fitted individually with Drayton TRV4 thermostatic valves. They are all about 10 years old.

I have just noticed that some of these valves have a problem - the adjustable body has by itself become partly detached, and is leaning out of the vertical, a gap having opened up at its base. Can this be repaired, perhaps by using a modern adhesive?

the plastic has gone brittle. replace them. you can buy the heads seperately.
