LK 419 Manifold Shunt is a shunt group with a thermal mixing

valve designed for systems equipped with a main pump.

The shunt group is suitable for both left-hand and right-hand

mounting directly to LK Heat Circuit Manifold.

LK 419 is equipped with an asymmetric mixing valve, LK 551

HydroMix, that has a thermal insert that controls the supply of

incoming and return pipe, so that the desired set temperature is

achieved.
