A single fluid control component featuring three ports allows for the redirection, mixing, or diversion of flow. This device enables a single inlet to feed one of two outlets, two inlets to combine into a single outlet, or diversion of flow from one inlet to either of two outlets. An example is seen in diverting coolant flow between a radiator and a heater core in a vehicle’s climate control system.
This components utility stems from its ability to simplify piping systems and reduce the number of components required for fluid management. Its integration can result in cost savings by minimizing the need for multiple valves and related fittings, while also reducing potential leak points. Historically, such components have played a crucial role in industries like chemical processing, where precise fluid control is vital.
The subsequent discussion will delve into the various types, operating principles, and selection criteria relevant to fluid control systems, with a focus on optimizing performance and ensuring reliable operation across diverse applications.
