Drayton TRV's

[rondbab]

I am trying to replace a couple of old Drayton TRVs (probably TRV2's or even earlier) but the current model, TRV4, has a different size connector (to the valve itself) to my original. Anyone have any idea where I might get hold of a new / replacement top for my old TRV?

Anyone know where / who the hell the manufacturers - Drayton - are? I've tried to find them but can't find a contact number or address.

Cheers

You can get TRV4 heads to go on trv3 bodies, which takes you back about 25 years! Part number is 0794012. Check your thread - trv3 is M30 x 1.5.
