The Rite-Temp® valve from Kohler (K-8304-PS-NA) is a complete valve body and pressure balancing cartridge designed for shower installations with PEX crimp connections (style F1807) and service stop valves. It automatically regulates temperature and offers built-in anti-explosion protection, keeping the output temperature at ±3 °F during pressure fluctuations. Its unique handle design and reversible monobloc cartridge simplify installation and maintenance, and it is compatible with all of the decorative accessories sold separately from Kohler.
