Under Sink Guardian® Mixing Valve With Cross Sense™ Technology - LFUSG-CS

The Under Sink Guardian LFUSG-CS thermostatic mixing valve is designed for point-of-use water temperature control in safety-critical environments including hospitals, schools, and senior care facilities. Crafted for installation beneath sinks or counters, this compact mixing valve helps reduce the risk of accidental scalding to provide reliable protection for vulnerable users.

The valve ensures temperature regulation with minimal pressure loss. Inside, dual check valves and strainers are contained in a replaceable cartridge assembly, promoting straightforward maintenance and long-term system sustainability. Color-changing temperature

indicators at the inlet points signal cross-connection anomalies.
