Boiler feedwater valves operate under severe service conditions and are subject to premature failure from seat leakage, cavitation, particulates, and frequent cycling. However, once the type and root ...

Compressible fluid flow through control valves will inevitably cause some form of flow-induced vibration in the fluid system. Identifying the type and cause of the vibration requires detective work.

Learning the basics can ease loop tuning frustration and ensure stability. During plant operations, it seems that tuning control loops is an ongoing task, which can be a continual frustration to ...
