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 varies when 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.

Installation Precaution:
1、All installations should be carried out by a Licensed Professional.
2、Install in accordance with markings on valve body. i.e. hot water inlet-marked H, cold water inlet-marked .
3、After temperature setting, if inlets temperature or fluctuates, outlet temperature variation is within +/-2 .
4、The external check valves at inlets prevent cross-flow of hotcold water when inlets is not the same.
5、If the ratio between two inlets is too large, one flow-limiting valve should be fixed at the side of higher .
6、Prior to installation, provisions should be made to flush the piping of any debris or foreign materials to ensure proper system operation.
