Diverter valves are processing valves designed to direct flow from an inlet to one of two or more outlets. They can also be used for flow control and to converge two lines into one. Diverter valves are primarily used to handle powders, dry solids and slurries, although some types are available that can handle liquid service. They are ideal for applications where the conveying or pumping of materials to multiple vessels or silos is needed.

Diverter valves are useful in flow control and pipeline circuits; as they may be operated in conjunction with other valves allowing for medium-to-high flow switching or metering control. The flow may be controlled through a variety of devices depending upon the application at hand.

Diverter valves are used extensively in a wide range of commercial applications including agriculture and farming, aviation and aerospace, chemical manufacturing and processing, construction, coolant, HVAC and cryogenic distribution, food processing, medical and pharmaceutical services, sanitation and waste processing, and water delivery.
