The HG115 LF thermostatic mixing valve offers the same reliable protection of the 110-D, but on a larger scale. A fast acting, high quality thermostatic element senses the outlet water temperature and reacts to maintain a stable delivery temperature even under changing flows or variations in supply temperatures. This Heatguard® valve also greatly reduces the outlet flow in the event of a cold water supply failure. The adjusting handle can be locked at a desired temperature or function in an adjusting mode. It is clearly marked to indicate the direction to turn to achieve hotter or colder water temperatures. The valve delivers water at a maximum of 120°F (49°C), allowing the heater to be set at 140°F (60°C) or higher, thus providing a greater effective volume of hot water and reducing the chances of legionella bacteria growth in the water. The maximum outlet water flow rate is 27.2 gpm, making it suitable for larger residential and commercial installations. Adj. outlet temperature range: 85-176°F (29-80°C)

Application: Widely used in large domestic and standard commercial water distribution systems: ideal for installation in a). hydronic radiant heating systems in conjunction with the water heating source to distribute tempered water to the system; and b), a hot water system at the water heater to distribute controlled temperature water.
