Thermostatic Mixing Valve

TM 50 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 KB 191 return flow retarder unit (see accessories) must be fitted to prevent cold water backfeeding and cooling the mixed water at the outlets.

Special Features
! 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 mixedwater setting
! The cold water inlet is automatically cut off if the hot supply fails
! Inner components are of scale-resistant materials
! Complies with KTW requirements

Range of Application
Flow medium: Water
Operating pressure Maximum: 10 bar
Maximum pressure difference between hot and cold inlet supplies: 2.5 bar
