Product Description

TM300 thermostatic mixing valves provide control of the water temperature and are used: - For centralised control on hot water supply units or for localised control adjacent to point-use outlets. Or for use with solar-heated hot water units with dual energy source. - In heating systems with underfloor heating or for limiting boiler return temperatures. Where a system includes a hot water circulation circuit, a KB191 return flow retarder unit (see accessories) must be fitted to prevent cold water backfeeding and cooling the mixed water at the outlets.

Additional Descriptions
  • Highly sensitive thermal element with good all-round water temperature sensing, even at low flow rates
  • Simple setting of the required water temperature
  • Scald protection - the hot water inlet is automatically cut off if the cold supply fails provided that the hot water inlet temperature is at least 10 K higher than that of mixed water setting
  • The cold water inlet is automatically cut off if the hot supply fails
  • Inner components are of scale-resistant materials
  • With inlet check valves
