4. What is the thermostatic mixing valve?

A Thermostatic Mixing Valve is a valve that blends hot water (stored at temperatures high enough to kill bacteria) with cold water to ensure constant, safe outlet temperatures preventing scalding.

They shut-off rapidly in the event of a hot or cold supply failure to prevent scalding or thermal shock.

TMVs accurately control water temperatures for bathing, showering and hand-washing. They maintain pre-set temperatures - even if water pressure varies when other appliances are used. TMVs can be fitted under baths and basins, be part of shower fittings, or as a feature of exposed hot and cold water mixers.


5. Usage of TMVs

Point of use mixing for wash hand basins, bidets, baths and showers in hospitals, schools, sport and leisure facilities, prisons and other public buildings.


6. Installation Precaution:

a.All installations should be carried out by a Licensed Professional.

b.Install in accordance with markings on valve body. i.e. hot water inlet-marked H, cold water inlet-marked C.

c.After temperature setting, if inlets temperature or pressure fluctuates, outlet temperature variation is within +/-2 C.

d. The external check valves at inlets prevent cross-flow of hot&cold water when inlets pressure is not the same.

e. If the ratio between two inlets is too large, one flow-limiting valve should be fixed at the side of higher pressure.

f.Prior to installation, provisions should be made to flush the piping of any debris or other foreign materials to ensure proper system operation.

What is the constant temperature?
Constant temperature is a constant temperature in a certain environment. Precise instruments are needed to measure the change of temperature at any time, and then adjust the temperature to make it always a temperature.


Thermostatic mixing valve?
Thermostatic valve is a warm system supporting products, widely used in electric water heater, solar water heater and heating water system. And the application in electric water heaters and solar water heaters, can automatically adjust the temperature according to the need of cold and hot water mixing, the required temperature can be achieved quickly and stable, ensure the water temperature constant, and is not affected by water temperature, flow, pressure changes, wash bath center solve problems when the cold water temperature sometimes hot and sometimes cold, interrupt hot water, water mixing valve can be automatically closed in a few seconds, play a security role.


Thermostatic valve choice?
The different applicability of different thermostat valves
Commercial large flow constant temperature valve: suitable for children's swimming pool, school, hospital, senior club, beauty salon center, bath center and other places.
