Kohler K-304-KS Rite-Temp pressure-balancing valve

Rite-Temp? pressure-balancing valve with screwdriver stops This 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, and screwdriver stops allow you to turn off the water supply at the valve.
