WATTS INDUSTRIES 3/4" Mixing Valve for Water Heater

Every year, thousands of people suffer serious thermal shock or scalding injuries in their bathtubs, sinks and showers. Additional untold numbers become ill due to water-borne bacteria, such as Legionella. Watts Thermostatic Mixing Valves maintain and limit mixed hot water to a desired, selectable temperature, helping to minimize thermal shock.

• This full flow valves is designed to maintain and limit the hot water to a temperature chosen by the installer
• Ideal for use in domestic water systems at the hot water source, such as boiler, water heater, tankless heater or storage tank
• Superior flow characteristics and exacting temperature control of the L1170 also make it ideal for radiant heat systems, commercial and industrial applications
• Specifically engineered for mixing hot and cold water on hot water supply systems
• Can be used for a variety of applications to reduce the temperature of the the hot water supply to the system
• Double-throttle design which combines the control of the hot and cold water to provide a sensitive response to changes in water temperature passing through the mixing chamber
