The 801 High-Low Thermostatic Mixing Valve provides tempered water over a wide range of flows in a single valve unit. Ideally suited for institutional and commercial applications such as group showers, schools, hotels, hospitals, prisons, and nursing homes. The 801 will provide from 1 to 50 gpm @ 45 psi (1/2 gpm when properly installed in a recirculated system). This valve provides three-way protection from scalding upon: 1) failure of the thermostat, 2) shut-off of hot water, or 3) shut-off of cold water. This one piece, single body valve contains a liquid filled thermostat, a stainless steel piston and liner, and is ASSE 1017 and CSA B125.3 approved. It is available with stop & checks, thermometer, shut-offs, cabinet assemblies, and a choice of rough bronze or white chrome finish. This single valve is easier to install, easier to maintain and more cost efficient than multi-valve systems on the market.
