Product Description

The principle of thermostatic radiator head is to use the temperature sensing element to control the size of the thermostatic radiator valve rise.

When the room temperature rises, the temperature sensing element expands and compresses the stem to close the valve.

Thermostatic radiator valve is made up of radiator valve and the thermostat to work independently of temperature control device.

When the room temperature is lower than the thermostat setting, hot water through the valve into the radiator, the room air is heated until the set temperature.

The liquid inside the thermostat will expand, push valve hot slice to seal the valve seat. Hot water no longer flow into the radiator,  the air is no longer heated.

As the room temperature drops, the liquid in the thermostat contracts, causing the valve to open again and the heating process to begin again, thus achieving a constant temperature cycle.
