3/4" NPT Union Mixing Valve (Heating Only)

The Honeywell AM-1 series accurately adjusts, maintains and limits the hot water temperature to a desired setting selected by the user. By installing a Honeywell AM-1 mixing valve and raising water heater storage temperature setting and limiting mixed outlet water temperature to safe temperature more usable hot water is available. In heating applications it provides comfort and protects the equipment. Multiple applications include heat pump systems, nursing homes, public facilities, automatic faucets, radiant floor heating, space heating, combo systems, solar hot water, greenhouses, and industrial applications.
