Danfoss RAS-CÂ² White & Chrome TRV & Lockshield 15mm Angled
I've fitted lots of these without any problems, I've also fitted the more expensive alternatives with no problems. It's more a cosmetic choice but if the valves are hidden then why fit the expensive "pretty" ones? The ability to isolate flow completely is useful on these valves, and they are bi-directional too. My preferred TRV as they offer quality and good value.

I spent sometime reviewing TRVs and selected this one. I have since purchased a number of these. It is the only TRV I will buy now. Bi-directional, simple to install and comes with various fititngs solutions so that you have a number of options. In four years never had one fail.

Overall it's a TRV - i chose this as it wasn't the cheapest but it wasn't the most expensive. It has one fault (IMO); if like me you don't like to drain a whole system for a quick radiator move/replacement and use a 15mm blank to cap the radiator 'tail', then you'll be dismayed that the standard 15mm blank will not attach to it as Danfoss have made the tail with a dimension of 15mm plus a Gnat's dangly bits!! A tad annoying! And hence only a 3 Star overall.
The 'chinzy' lockshield with the âhiddenâ allen key valve looks a lot nicer than the white plastic knob of other valves. However, this might not suit you if a disaster ensues and in a rush you have to find the correct allen key!
On the plus side, the TRV valve can be arranged both horizontally and vertically and the direction of flow does not matter with the valve as it has a simple adjustment to account for the direction of the flow you need.
Performance and reliability are hard to assess after one week. Only time will tell.

Good quality valve
Appears to be an excellent quality valve, only time will tell though as this was purchased as a replacement for a well known brand that had badly corroded.
I liked the clear instructions especially those related to the setting for the bi-directional flow valve.
