Hi folks need to install 3 new radiators and I am looking for decent trv valves.
I have been advised to have the ones with vertical drains so we can drain the radiator down and lock shield.
These are the 2 I have found so far

http://www.bhl.co.uk/product/PEGLER_TERRIER_II_15MM_TRV_CP_367_DLS
Are these any any good are what's the different between the rt 414, rt212 or tvr 4.
Am I after the right things or is there a better make or a more cost effective one.
Many thanks
Jon
