For domestic water systems.
The 115-D incorporates a fast acting, high quality thermostatic element that senses the outlet water temperature and reacts to maintain a stable delivery temperature even under changing flows or variations in supply temperatures. The valve also greatly reduces the outlet flow in the event of a cold water supply failure. The 115-D features an adjusting handle that can be locked at a desired temperature. Alternatively it can function in an adjusting mode, with the handle clearly marked to indicate the direction to turn to achieve hotter or colder water temperatures.
The Heatguard 115-D is intended for installation at the water heater to distribute controlled temperature water throughout a domestic hot water system. 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 legionellae bacteria growth in the water. The valve flows 30 gpm at 45 psi, making it suitable for larger residential and commercial installations.
Sizes (base valve):
3/4 and 1
The 115-D is certified to ASSE 1017 and CSA B125 and is listed by ASSE and IAPMO.
