How do anti-scald valves work?

Anti-scald valves, also known as thermostatic mixing valves, work by blending hot and cold water to achieve a safe and consistent water temperature. These valves typically consist of a temperature-sensitive element, such as a wax capsule or a thermostatic cartridge, and a mixing chamber.

When hot water flows through the valve, the temperature-sensitive element senses the temperature and adjusts the position of the valve accordingly. If the water is too hot, the valve reduces the flow of hot water and increases the flow of cold water to achieve the desired temperature. Conversely, if the water is too cold, the valve decreases the flow of cold water and increases the flow of hot water.

The valve continuously monitors and adjusts the water temperature to maintain a safe and comfortable level. This allows users to be protected from scalding by preventing sudden fluctuations in water temperature.
