The main function of a TMV is to mix hot and cold water in a way that ensures the output water temperature remains consistent, typically at a preset temperature. It achieves this by using a thermostatic element, such as a wax cartridge or a bimetallic coil, to sense the temperature of both the incoming hot and cold water. When these temperatures fluctuate, the TMV automatically adjusts the proportions of hot and cold water to maintain the desired set temperature.

Mixing Process: Inside the tempering valve, the hot and cold water streams are mixed together to achieve the desired temperature. The valve has an adjustable setting that allows you to control the temperature of the mixed water.

Thermal Disinfection Valves: These specialized tempering valves are used in healthcare and institutional settings to facilitate thermal disinfection cycles. They can raise water temperatures to levels that kill bacteria and pathogens within the plumbing system.

Scald Prevention: By continuously monitoring and adjusting the water temperature, the tempering valve prevents scalding incidents, providing a reliable safety measure, particularly in settings where vulnerable individuals, such as children or the elderly, may be at risk.

Safety: If there is a sudden failure or interruption in either the hot or cold water supply (for example, if someone flushes a toilet), the tempering valve is designed to respond quickly to maintain a safe temperature. It will automatically adjust the flow of the available water to maintain the desired temperature.
