As explored in the first part of this article, extreme vibrations around control valves can potentially lead to hazardous noise levels, impaired valve performance, and potential damage to valve internals and piping systems— even when the valve itself is not the root cause. This article continues to explore the sources of vibrations, risks, and strategies end users can utilize for effective mitigation.
Flow induced vibration (FIV) inside a valve can create a condition called buffeting. In this case, flow turbulence within the valve body creates localized low-pressure zones and pressure fluctuations.
