A simple thermostatic actuator serves for optimum temperature comfort in the room. The actuator controls the radiator valve according to the set temperature and thus control the flow of medium in the radiator. The actuator works on the principle of a liquid sensor, which expands the liquid at rising temperature and pushes the bellows that closes the valve. When the temperature drops, the function is reversed - the liquid loses volume and allows the valve to open and fluid flow in the body.

Separate temperature sensor

The actuator with a separate sensor can be installed wherever the conditions for using the standard head RTN51 are not suitable. The temperature sensor is connected to the thermostatic actuator by means of a capillary. Installation of the sensor is possible according to the following rules:
