What they havent explained is that this is normal. (bad for valves), but normal.
whenever the pressure drop across the valve (deltaP DP), exceeds the vapor pressure at that temperature, there will be cavitation.
The potential damaging effects is when you have catastrophic collapse of the bubble stream on the surface of the valve. This causes spalling and stress cracks on the surface.
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.
