Amberley Radiator Valves are traditional period style TRV valves. Amberley valves have a real wood head and frost protection as standard. Antique styling makes them ideal for cast iron radiators. The lock-shield design allows for easy adjustment with a large flat head screwdriver. Amberley radiator valves are made from solid brass and available in Chrome, Brass, Black Nickel and Satin (Brushed) Nickel.
