Danfoss RAS-DÂ² Chrome TRV 8/10/15mm Straight & L/S
Watchout for the lockshield
had this product installed for 6 years I had to wind down both the TRV and the lockshield to isolate several RADs for some maintenance. Horrified to find on re-commissioning that the lockshields have leaked.
This has happened so far on 4 RADS
according to Danfoss this is because theres an internal O ring which corrodes over the years and cannot be replaced
the internet implies if you buy a lockshield with a 'glandnut', you stand a better chance of servicing it if something goes wrong
Whilst i'm not an expert, to me a lockshield is a fundamental part of RAD maintenance. it should be able to seal off the RAD then open it up again for many years. Afterall, if a TRV can be turned up and down and switch off and on without leaks why can't the lockshield be designed to do the same?

Lovely TRV from a quality brand. We made the mistake of buying a cheap TRV with our new towel radiator which used to always make a knocking noise when the valve didn't close. Replaced it with this one and we have had no problems and the bathroom is kept at a regular even temperature. Would agree that the temp settings are faint but not a major issue.

Very nice and easy to fit. Stunning chrome finish. Fitted one set about a year ago and have had no problem at all. Writing this review as I am just about to order a second set.

top quality product the only small fault i found is in the setting marks on the valve, they are a bit light to see easly. if they were a deeper colour this valve would be perfect
