Control Valve Flashing And Cavitation at Maya Reed blog

Control Valve Flashing And Cavitation. Unanticipated cavitation can destroy a control valve’s internals and even result in catastrophic failure, so it is important to understand what cavitation is, why it occurs, and how to address it in control valve applications. The liquid pressure decreases below vapor pressure creating vapor bubbles. Due to local conditions in a valve cavitation may start on much higher outlet pressures. Flashing shares some common features with choked flow. Cavitation can be avoided by using more than. The first stage of cavitation and flashing is similar; Flashing occurs when liquid flows through a control valve and vaporizes, remaining a vapor. Flashing is not the same as cavitation. Control valve cavitation is the sudden vaporization and condensation of a liquid downstream of the valve due to localized low pressure zones. Most control valve manufacturers provide cv tables by size for their valves which provide the cv value for every 10% of opening.
