A diverter valve is a mechanical device used to control the flow of fluids in a system. It allows the user to redirect the flow from one path to another, making it essential in various applications, such as plumbing, heating, and industrial processes. By adjusting the valve, you can choose which outlet the fluid will travel through, ensuring efficient operation. These valves come in different types, including ball valves, gate valves, and check valves, each designed for specific functions. Diverter valves are commonly found in shower systems, where they switch the water flow between the showerhead and the faucet. Their versatility makes them crucial in many fluid management systems.
