Prevent cavitation in control valves with this new trim design

| By Chemical Engineering

Valtek DiamondBack is a new anti-cavitation trim design for control valves in severe-service applications. This technology Flowserve Cloudeliminates high-pressure-drop cavitation damage and the associated noise. In addition, the DiamondBack design can be produced in a range of materials, including tungsten carbide, effectively mitigating the effects of erosion. According to the manufacturer, DiamondBack also delivers up to 30% higher flow than comparable multi-stage valve trim with the same pressure drop, which in some applications, results in a smaller and lighter package than other designs. DiamondBack cavitation-elimination technology is available for installation in new or existing Valtek Mark Series control-valve body sizes. DiamondBack is able to pass slurries and entrained solids up to 15 mm without plugging. — Flowserve Corp., Irving, Tex.
