Anti Cavitation Diffuser Device

The Anti Cavitation Diffuser (ACD) is a device designed to prevent cavitation damage at source, also reducing noise levels and vibration. This device replaces traditional anti-cavitation trims, and will prevent flashing and cavitation pitting of valves and piping operating at high pressure differentials. The ACD should be installed at the outlet downstream of Pressure control or Pressure Relief valves thereby controlling the pipe velocity profile and the pressure characteristic across the control valve seat. Effectively silencing and eliminating cavitation and minimizing erosion damage, the ACD will significantly extend operating life and minimize downtime in applications working in severe service conditions.
