Thermostatic Mixing Valves
TM50 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.
With male connections
Accessories
Thermostatic mixing valves of this type are used for central regulation of the water temperature in
solar-powered, bivalent water heaters.
A cold water break can be fitted in the circulation line in water heater systems, which prevents cold
water from mixing at the extraction point via the circulation line.

Additional description • 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
