Abstract
Critical cavitation indices are presented for a 12-in. ball and a 12-in. butterfly valve installed in a closed conduit system with, a sudden expansion downstream of the valves. Tests were conducted under normal operating conditions. In addition, tests were conducted to find the effect of injecting air and water at various locations on the critical cavitation index. It was found that injecting water into the sudden expansion below the valves does not affect the cavitation. However, injecting small quantities of air into the separation zones below the valves does materially reduce the cavitation intensity and hence the critical cavitation index.
