Point-of-Use Thermostatic Mixing Valve, 3/8 In M x M Comp, 0.25 and 2.5 GPM, 80–120°F, ASSE1070, LFUSG-B Series

This 3/8 inch Under Sink Guardian^® lead-free thermostatic mixing valve is designed for precise control of mixed hot water at the point of use, helping reduce the risk of accidental scalding in commercial and residential plumbing systems. It is commonly installed under sinks in kitchens and bathrooms where controlled water temperature is critical for occupant safety. Engineered with a lead-free brass body, the valve features male compression connections that allow for straightforward installation between shutoff valves and the faucet. Its internal copper thermostat continuously balances hot and cold water supplies to maintain a consistent outlet temperature even when inlet conditions fluctuate.

The valve offers an adjustable outlet temperature range from 80 to 120 degrees Fahrenheit, with field adjustment performed during installation. Built-in check valves help prevent crossflow between hot and cold water lines, protecting the overall plumbing system from pressure imbalances. Integral stainless steel strainers with forty mesh screens are incorporated to filter debris from the water supply, helping maintain performance over time and reducing the likelihood of system fouling. This makes the valve well-suited for facilities teams seeking dependable temperature regulation with minimal maintenance. With a maximum working pressure of 150 psi and a flow range suitable for low-demand fixtures, this thermostatic mixing valve supports compliance with common plumbing safety standards for point-of-use temperature control. It is an effective solution for offices, healthcare facilities, and multi-tenant buildings requiring reliable hot water tempering.
