A diverter valve is a plumbing or mechanical valve that directs fluid flow between two or more outlets within a system.

A diverter valve is a device used to redirect the flow of water, air, or other fluids from one pathway to another within a plumbing or mechanical system. Instead of stopping flow, it changes the direction, allowing a single supply line to serve multiple outlets or functions.

In construction and plumbing applications, diverter valves are most commonly found in showers and tubs, where they switch water flow between a tub spout, showerhead, or handheld spray. They are also used in hydronic heating systems, irrigation setups, and some HVAC applications to control where fluid or air is delivered.

Proper selection and installation of a diverter valve are critical for system performance and user convenience. Valves must be compatible with system pressure, temperature, and material requirements, and they must be installed in accessible locations for maintenance or replacement. Poorly installed or low-quality diverter valves can lead to leaks, pressure loss, or inconsistent flow control.

Early diverter valves in plumbing were simple mechanical plugs, but modern designs can precisely control multiple outlets with a single turn or push.
