Danfoss RAS-CÂ² White & Chrome TRV & Lockshield 15mm Angled
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.

Very well priced TRV with lockshield. I brought these on a promotion just when it so happened I was in need of some TRV's.
Control of the TRV has a nice feel and the added benefit of a sealed lockshield prevents tampering once the system has been set.
Overall a very nice TRV.

Best TRV On the Market
It may be more expensive than others but with the revolver head it is the only true unidirectional valve on the market. I have fitted these since they were brought out and never had any problems.
