What is the main use of a three-way diverting valve?

A three-way diverting valve serves the primary function of redirecting flow between two outlets. This type of valve has three ports: one inlet and two outlets. By adjusting the valve, fluid can be directed from the inlet to one of the two outlets, enabling the control of flow within a system.

This functionality is crucial in various HVAC applications, where there is often a need to divert heat or cooling from one area to another based on demand. For example, in a hydronic heating system, a three-way diverting valve can manage the flow of hot water either to a radiator or to a tank, depending on which requires heating at that time.

The ability to seamlessly redirect flow makes it an essential component in maintaining system efficiency and performance, allowing for better temperature control and distribution without the need for complex system alterations. This versatility is what distinguishes it from other types of valves that may not offer the same dual-outlet functionality.
