Thermostatic Mixing Valve

The Demax Thermostatic Mixing Valve is a device that blends high-temperature hot water (sufficient to kill bacteria) with cold water to maintain a consistent, safe outlet temperature—preventing scalding. It shuts off rapidly if hot/cold supply fails, accurately controls pre-set temperatures (even with fluctuating water pressure), and is suitable for baths, showers, and hand-washing in domestic/public settings.
