The thermostatic head is a regulating element of heating systems. It is designed to automatically control the air temperature in rooms heated, for example, by means of convectors or radiators (when the head is mounted on a thermostatic valve). The MVI thermal head has a built-in liquid temperature sensor. The temperature controller automatically maintains the air temperature in the room, corresponding to the setting value of the thermal head. The bellows capacity of the thermal head, when the air temperature changes, acts on the valve stem, thereby changing the amount of coolant passing through the heater. The use of thermostats allows you to automatically maintain the air temperature in the premises at a given level with an accuracy of 1°C.
