The valve is controlled by the temperature of the media. With an LK 821 ThermoVar installed in, for example, a solar heating system an optimal stratification in the storage tank is obtained. LK 821 can be equipped with an insulation - see under Accessories. For more information, please see the product sheet for insulations page 49. The valve can be mounted at any angle. LK 821 ThermoVar can easily be adapted for right- or left-hand mounting.
