Cavitation in a globe valve

2 mm 0.4 bar reverse

opening: 2mm
downstream pressure: 0.4bar

This movie, as the flow rate increase, shows cavitation inside a Plexiglas model of a 2" globe valve typically used in nuclear power plant.

thanks for taking the time and effort in making this video the plant management can now see what there valves and piping goes through on a day to day bases

En este ejemplo se asume q la valvula se esta cerrando por lo cual ocurre un estrangulamiento para q se genere el fenomeno d cavitacion. Pero xq en la eskina derecha muestra un aumento del caudal ???

That is an excellent video to demonstrate cavitation, thank you. We will recommend Bürkert Pacific's staff and customers have a look at this to understand why correct valve specification is crucial.

what is the thermal @ 5.5 bar?
