Rated 5 out of 5 by from Good Quality and Value. Easy to Fit great for Isloating the water supply to the radiator to remove for decorating especially for tall vertical radiators

Rated 5 out of 5 by from Tails don't wag I have used these ball valves wherever feasible on the new replacement radiators fitted on a room by room whole house refurbishment. The greatest advantage being to lock within each radiator it's fluid content. That equates to less system draining and as the mix includes inhibitor less waste and replacement savings
