HydroMix domestic water mixer with check valves

LK 551 Hydro Mix is ​​an asymmetric mixing valve for hot water preparation as a domestic water mixer and for heating systems. The LK 551 domestic hot water mixer It has a thermal insert for regulating the hot water temperature. It regulates both the hot and cold water supply to achieve the desired temperature. The valve has an anti-scald device that interrupts the flow of hot water if the cold water supply fails. The domestic water mixer Requires no maintenance. Check the installation regularly.

The valve wheel is used to set the desired hot water temperature within the control range. The protective cap prevents accidental changes to the temperature setting. When installing on a boiler/storage tank with a built-in water heater, a gap should be left between the valve and the boiler/storage tank to prevent thermal radiation from impairing the valve's function.

The arrow on the valve body indicates the flow direction.
C = incoming cold water
H = incoming hot water
M = outgoing hot water
