This post will discuss the various failure modes associated with control valves and how to detect them. We will look at the different types of failures that can occur, from the more common issues of poor calibration or stuck valves, to those more difficult-to-diagnose faults such as latching or coking. We’ll also explore potential causes for each type of failure and how best to remedy them. Finally, we’ll consider ways to better monitor control valves and keep them functioning correctly over time.
