Product Overview
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 - An added feature incorporates check valves in both the hot and cold water inlets to protect against cross flow - Minimum flow requirements to maintain set temperature
- Valve size: 3/4" with solder connections FEATURES: - ASSE standard 1017 listed - Integral check valves - Proportional flow design - controls both hot and cold supply to the mixed water outlet - Superior flow characteristics: - Low pressure drop- Accurate temperature control - Easy installation - union solder - Heavy duty rugged construction - Made from brass castings - Repairable - uses replaceable elements - Energy saving design by extending the amount of hot water available - Solid wax hydraulic principle thermostat assures dependable mixing of hot and cold water
