Four-Way Mixing Valve
A four-way mixing valve is an essential component of any EKO boiler installation. When properly
installed, it allows hot supply water to be automatically mixed with cooler return water to avoid low
return later corrosion at the boiler return water connection and maintain a relatively stable boiler water
temperature. Four-way mixing valves also make it possible to maintain a steadier house temperature
and can be used in either gravity or pumped hydronic systems.
