The Lead-Free Bronze-Thermostatic Mixing Valves (TMV) are specifically designed for mixing hot and cold water on hot water supply systems. They can be used for a variety of applications to reduce the temperature of the hot water from the system, and are ideal for radiant heat applications. This Model features a “double throttling” 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. A thermostatic mixing valve blends cold water with hot water that is conventionally stored at high temperatures for kill bacteria for ensuring safe and constant outlet temperatures that prevents scalding.

To a temperature pre-selected by the user or installer, hot and cold water entering the valve is mixed. Inside the body of the valve, the amount of incoming hot and cold water is automatically proportioned by a thermal-sensitive mechanism for producing the needed mixture. The mechanism then automatically compensates for any reasonable variations in supply pressures or temperatures within the design range to maintain the pre-selected temperature. In the case of cold water supply failure, the thermostatic mixing mechanism will automatically shut down the flow to present discharge of dangerously hot water. During the case of the failure of hot water supply, the flow will also be shut down for preventing thermal shock. During a sudden surge of supply temperature, the TMV will adapt swiftly and deliver water at a temperature that is safe enough.

Safe storage and distribution of domestic hot water are imperative in any application. We provide a complete line of thermostatic mixing valves to ensure safe, tempered water is delivered from the source to use.

Advantages –

  • Assures constant outlet water temperature even with variations in hot or cold water supply temperature.
  • It allows the water heater to be operated at higher temperatures, extending the effective system flow rate and preventing the growth of Legionella.
  • It can reduce the size/BTU requirements needed to provide capacity for peak system demands.
  • Assures constant safe hot water temperature at the point of delivery to the fixture.
