The product outline is a special valve for radiator, which consists of constant temperature controller and valve body. Users
rotate the constant temperature controller to the required setting temperature. When the indoor temperature exceeds the set
temperature, the thermostat inside the thermostat (filled with temperature-sensitive medium) expands by heat, and the volume of
the thermostat is large, which promotes the pole. When the indoor temperature is lower than the set temperature, the thermostat
shrinks and the volume decreases. The valve core reset spring pushes back to the valve stem, which makes the valve open larger and enlarges the water inflow of the radiator until the room temperature reaches the set value, and the indoor temperature can be
set according to the requirement.
