Thermostatic Radiator Valve

A thermostatic radiator valve (TRV) is a self-regulating valve fitted to a hot-water heating system radiator to control the temperature of a room by adjusting the flow of hot water to the radiator. The classic TRV contains a plug, typically made of wax, which expands or contracts with the surrounding temperature. This plug is connected to a pin, which in turn is connected to a valve. As the temperature of the surrounding area increases, the plug expands, gradually closing the valve and limiting the amount of hot water entering the radiator, thereby controlling the room temperature. TRVs are available in various designs, including manual, mechanical, electronic, and smart versions, each offering different features for temperature control and energy efficiency. Danfoss A/S, a Danish multinational company, is a leading manufacturer of TRVs, providing a range of products designed to enhance heating system performance and energy savings. (danfoss.com)
