KOHLER K-304-K-NA Rite-Temp Pressure Balancing Valve
Rite-Temp pressure-balancing valve works behind the scenes to prevent scalding and freezing for a safe, comfortable water supply. The valve features a high-temperature limit stop and an optimal comfort zone, so you can set a maximum high and then find and maintain your desired water temperature. Additionally, the unit has a diaphragm design that virtually eliminates freeze-ups from contamination and water debris. Universal NPT and direct sweat connections need no additional parts for installation.
