SMR Bathrooms stock the complete range of Bentley traditional radiator valves, for super fast next day delivery throughout the UK from our own stock. The Bentley TRV is a solid brass radiator valve available in five surface finishes; polished brass, antique brass, antique copper, chrome and black nickel. We also stock the sister range which is the Gothic TRV available in antique brass and silver brushed nickel. The thermostatic function means that the valve will adjust to the fluctuating room temperature, so as the room cools, the valve will open to increase the heat output of the radiators and as the room heats up the valve will automatically close down to reduce then stop the flow of water and maintain a comfortable room temperature. As the UK's biggest retail stockist we cannot be beaten on price or service. Call today to place your order.
