The thermostatic head is mounted on a thermostatic radiator faucet to work with it as a thermostatic controller.
Operating principle: A change in room temperature affects the volume of liquid contained in the thermostatic head’s reservoir. The change in volume causes the internal mechanism to move, with a corresponding closing or opening of the valve and consequently a modulation of the flow of the heating fluid to the radiator. When the desired room temperature is reached, the head gradually closes the valve, leaving a passage for a minimum amount of water to maintain a constant room temperature and save energy. The use of thermostatic heads allows you to automatically maintain the room temperature at a predetermined level with an accuracy of 1℃.
