The radiator thermostatic balancing valve is a self-operated constant temperature flow control valve mounted on the radiator. It is composed of a thermostatic valve body and a temperature regulating device for air temperature sensing. The principle of action is that the opening of the thermostatic valve body is automatically controlled to change the amount of hot water passing through the radiator. When the room temperature is lower than the set temperature value, the radiator balancing valve automatically opens (or gradually increases) the radiator to heat the room until the room temperature reaches the set value. When the temperature of the room rises, the temperature sensor pack expands, causing the valve to gradually close (or close), and the heat sink will reduce the heating speed (or stop heating). Simply put, the main function is energy saving and comfort. However, many ordinary customers only use ordinary temperature control valves without a temperature pack, which cannot be automatically turned on or off. It is recommended that everyone adjust the indoor temperature and ensure that the indoor temperature is always at the set temperature by adjusting the hot water flow into the radiator. This thing is necessary for today's energy-efficient buildings. Designing houses and public buildings is a form of radiator heating. At this stage, it is necessary to use a three-way connection with a temperature control valve.
