3D Printed Valve Part Helps Prevent Cavitation | The Cool Parts Show #56 

Water or other fluids moving at a high flow rate through a control valve can be subject to cavitation able to damage pipes downstream. The solution was known decades ago: Divide the flow into an array of many much smaller parallel streams. Unfortunately, the geometry required to realize this effect resulted in a part that was difficult to produce - to the point that an early anti-cavitation product for ball valves was discontinued. Now, additive manufacturing has overcome this challenge. The Emerson company produces its Fisher Cavitrol Hex anti-cavitation trim in an essentially unattended process through laser powder bed fusion, and so far about 600 of these components have been installed in industrial ball valve applications.
