Mixing Valve Overview Addressing The Dangers of Hot Water Every year, thousands of people suffer injury or become ill as the result of water stored or used at inappropriate temperatures, leading to the potential for: • erious thermal shock and scalding injuries suffered in bathtubs, sinks, S and showers • Illness caused by water-borne bacteria such as Legionella Thermal Shock • ne source of injuries in the shower is slips and falls in reaction to a sudden O increase or decrease in water temperature, known as thermal shock. • f the supply of cold or hot water is lost, the water flow should...

Mixing Valve Overview Advantages of Watts Thermostatic Mixing Valves Since 1874 Watts has set the standard for valve technology. Watts thermostatic mixing valves: • Maintain and limit mixed hot water to a desired, selectable temperature • rovide a way to control outlet temperatures to help mitigate the risk posed by P unmonitored, untempered water • nable safe, accurate control of hot water from its source through to its final E use, regardless of how the supply temperatures or pressures vary over time • rovide more precise control than pressure balancing mixing valves, which do P not...

Mixing Valve Overview How Watts Mixing Valves Work • nce tempered water is in use, a thermostat in the mixing chamber of O the valve senses the outlet temperature and automatically positions a seat assembly, which controls the flow of hot and cold water supplied to the mixing chamber. • f the mixed outlet temperature increases, the thermostat will expand, movI ing the seat assembly to allow the cold water inlet port to open more fully and at the same time restrict the hot water inlet port. • onversely, if the mixed outlet temperature decreases, the thermostat will C contract, moving the...

At the Fixture • eat loss in the system piping can result in varying temperatures of the hot H and cold water supplied to fixtures. The use of thermostatic mixing valves helps ensure the selected mixed-water temperature at the point of delivery to the fixture. In Supply Systems • he water temperature discharged directly from a water heater can vary by T ±10°F or more. This can be attributed to tolerance of control devices, inlet water temperature changes, and/or stacking (higher water temperatures at the top of the water heater). • sing a thermostatic mixing valve helps ensure constant...
