What are the main differences between mixing and diverting three-way valves?

Mixing three-way valves combine two incoming streams into one outgoing stream, while diverting three-way valves split one incoming stream into two outgoing streams. The common port of a mixing valve is the outgoing stream, whereas the common port of a diverting valve is the incoming stream. Understanding the differences between these two types of valves is crucial for selecting the right valve for a specific application.
