Three-way mixing valve 1 1/4″ vk 55-70 °C (DN32 KVS 9) LK Armatur

LK 823 ThermoVar® R is a 3-way thermal loading valve for solid fuel/tank installations. The valve is designed both to ensure optimal temperature stratification in the tank and to maintain a high return temperature to the boiler, thereby increasing system efficiency. Tar and condensate formation is prevented, which extends the boiler service life.

The valve regulates two ports, which means that no balancing valve is needed in the circuit between the boiler and the loading valve. The thermostat begins to open port A when the temperature of the mixed water leaving port AB reaches the opening temperature. Port B closes when the temperature in port A exceeds the nominal opening temperature by 10 °C.
The valve can be adjusted within a range of 55 °C to 70 °C.

The valve can be installed at any angle. LK 823 ThermoVar® R is designed for right- or left-hand installation.
