What is Valve Cavitation? (Animation)

Learn about valve cavitation and how damage can be reduced or prevented.

Key Points:
– Cavitation occurs when the fluid vaporizes then returns to a liquid state as the pressure increases downline.
– Cavitation can cause unacceptable noise and vibration that reduce efficiency or lead to loss of process control.
– Cavitation damage can be reduced by altering or accommodating valve construction materials or staging pressure drops.
