Thermostatic mixing valves are used to maintain the domestic hot water supplied to the user at a constant and safe temperature, when variations in the hot and cold water supply conditions and draw off flow rates occur.
The failsafe design shuts off the mixed water flow automatically in the event of disruption in the hot or cold water supply to the valve

The merchant range of fail safe thermostatic mixing valves have been designed and manufactured to meet the requirements of BS 7942:2000 and the National Health Service model engineering specification D08 for use in healthcare premises, hospitals, care homes, and schools.

BS EN 1111: 1999 and BS EN 1287: 1999 and the TMV2 Type Scheme

Basin, Bath & Shower Valves

A range of thermostatically controlled mixer valves all capable of operating with a hot/cold or cold/hot pressure ratio imbalance of up to 10:1,All units incorporate check valves to prevent cross-flow between supplies, and strainers to reduce damage due to contamination.,Connections are via the compression fixings using either 15 or 22mm pipe.
