Abstract

Valves are used in piping systems to control flow rates and to regulate pressures. Whenever a large pressure drop occurs across a valve, the possibility of cavitation exists. A system can be subject to noise, vibration, and erosion damage when operating in a cavitating flow range. To quantify these effects in terms of different stages of cavitation, this paper presents design limits and testing procedures for cavitation in valves. The author hopes that such design criteria will be included in future testing specifications such as those in the Instrument Society of America ISA-S39.2.
