The Amberley range are period styled TRVs; They come with all the features you would expect, like a real wood head, austere styling and the typical frost protection a TRV provides. They differ from other valves of this style with an impressive chimney design lock-shield that allows for easy adjustment with a large flat head screwdriver. Made from solid brass and available in Chrome, Brass, Black Nickel and Satin (Brushed) Nickel.
