Cavitation Limits for Valves
To quantify pressure effects in terms of different stages of cavitation, this paper presents design limits and testing procedures for cavitation in valves. All of the cavitation testing involved data gathered from accelerometers (sensing devices) and aural observations. Evaluations of pressure drops and flow coefficients were derived from static wall taps placed in the piping upstream and downstream from the test valves.
