Solar Water Heater Accessories Thermostatic Mixing Valve
What is the thermostatic mixing valve? A Thermostatic Mixing Valve (TMV) is a valve that blends hot water (stored at temperature high enough to kill bacterial) with cold water to ensure constant and safe outlet temperature preventing scalding.

Usage of thermostatic mixing valve:
Point of use mixing for wash hand basins, bidets, baths and showers in hospitals, schools, sport and leisure facilities, prisons and other public buildings.
Thermostatic Mixing Valve 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 Celsius degree.
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.
