The Danfoss Midi shunts are used for control of flow and supply temperature in hydronic floor heating systems. The compact, midi shunt comes premounted for 1-circuit ready to mount on the wall and fittings for pipe connection (20 × 2 mm). The shunts self-acting proportional thermostatic control valve is used to control the supply temperature. The thermostatic sensor ensures that the desired supply temperature to the underfloor heating system always remains constant.
