3-Way Thermostatic Mixing Valve (High Flow)

This 3-Way Thermostatic Mixing Valve ( $\text{TMV}$ ) is a high-precision, high-flow temperature control device designed to provide a stable and safe water temperature automatically. Its advanced sensing mechanism makes it ideal for large-volume, central hot water supply systems, group showers, or industrial applications.

💡 Working Principle

The valve achieves its constant output temperature using a highly sensitive thermal element located at the mixed water outlet:

Sensing and Actuation: A thermosensitive component is installed at the mixed water outlet of the valve body.
Automatic Modulation: Utilizing the characteristics of the sensing element, it automatically pushes the internal spool to move, thereby simultaneously blocking or opening the cold and hot water inlets.
Constant Output: Once a temperature is set via the control knob, the proportion of cold and hot water entering the outlet automatically changes to instantaneously compensate for any fluctuations in the inlet temperature or pressure of the supply lines. This ensures the output temperature remains constantly stable at the set value.
Adjustable Range: The temperature adjustment knob allows for setting the temperature anywhere between $35^\circ\text{C}$ and $65^\circ\text{C}$ , and the $\text{TMV}$ automatically maintains this set temperature.
