How Does A Thermostatic Radiator Valve  Works?

The sensor element of BEIJINSI thermostats consist of a liquid filled metal capsule with an immersed below and integral push rod. A temperature fluctuation leads to an alteration of volume of the liquid which entails a length modification of the immersed below. Then the valve is closed and opened by the push rod.

When the room temperature exceeds the set temperature, the liquid sensor element in the thermostatic head expands and increases it’s volume. It pushes the valve’s stem to turn down the valve, to reduce the hot water flow of the radiator and make the room temperature reach the set temperature. When the room temperature is lower than the set temperature, the liquid sensor element shrinks and the volume decreases. The returned spring in the valve core pushes back the valve stem to open the valve and increase the hot water flow of the radiator until the room temperature reaches the set value.

With these energy efficient trv valves, the temperature in each room of the home is easily controlled, reducing energy usage and saving money by avoiding overheating commonly caused by manual valves. A compression connection and PTFE seal are recommended for installation.
