3 or 4 Inch DN20 Solar Heater Thermostatic Mixing Valve Pipe Valve Building Materials Standard Medium Pressure Thermostatic mixing What is the thermostatic mixing valve A Thermostatic Mixing Valve is a valve that blends hot water 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.One way valves:Tow inlets have one way valves,1 Fail-safe on Hot or Cold Supply Failure,2 Delivers Stable Mixed Water Temperature,3Extended Mix Temperature Range : 35-55 Celsius,4Idea for Domestic and Public Water Application,5Tamper-Proof Cap Temperature setting range:38-45 Celsius Hot water inlet temperature range:55-80 Celsius Cold water inlet temperature range:5-29 Celsius Maximum working temperature:99 Celsius Temperature stability:2 Celsius Pressure:Medium Pressure Model Number:NO Standard or Nonstandard:Standard Temperature of Media:Medium Temperature Media:Water Actuator Mode:With Instruction Inlets: M, Outlet: M Flow rate(1 kg pressure drop):26.67 L or min colour:Silver and black Material:copper size:9.8x7.9x4.8cm Connections: BSP,3 or 4 inch DN20 Package Contents: 1xThermostatic mixing valve Installation Precaution: 1All installations should be carried out by a Licensed Professional. 2Install in accordance with markings on valve body. i.e. hot water inlet-marked H, cold water inlet-marked C. 3After temperature setting, if inlets temperature or pressure fluctuates, outlet temperature variation is within 2 Celsius. 4The external check valves at inlets prevent cross-flow of hotandcold water when inlets pressure is not the same. 5If the ratio between two inlets is too large, one flow-limiting valve should be fixed at the side of higher pressure. 6Prior to installation, provisions should be made to flush the piping of any debris or other foreign materials to ensure proper system operation.
