Cavitation Erosion Example - Over-Center Valve Spool

This is an example of how cavitation can damage hydraulic components. In this case, it's a spool from an over-center valve. The erosion crater is hidden, and is almost 4-mm deep! More on this interesting phenomenon in my post on "Cavitation in Hydraulic Systems".
