A three-way mixing valve is characterized by:

A three-way mixing valve is designed to control the flow of fluids by blending them from two different sources into one combined output. This setup relies on the presence of two inlets, where each inlet receives fluid from a separate source, and one outlet, which delivers the mixed fluid to the downstream system.

In practical applications, this type of valve is crucial for temperature control in HVAC systems, where it can mix hot and cold water to achieve the desired temperature for heating or cooling. By adjusting the flow rates of the two inlets, the valve can effectively control the ratio of the mixed output, ensuring optimal performance and energy efficiency.

Understanding the configuration and function of a three-way mixing valve is vital for anyone involved in systems that require precise fluid control, making it a fundamental concept in instrumentation and controls.
