Imagine you have been tweaking and tuning one of your control loops and have the perfect PID [proportional-integral-derivative] settings. Everything is working great for several months until it isn’t. Chances are that it’s the part of that loop doing all the manual work to keep the process running smoothly—the control valve. A poorly performing control […]

An Asian refiner sought to improve reliable operations around their control valves a decade ago. I caught up with Emerson’s Sumitaka Ichiki who shared the story of their journey to more reliable operations. Using the Fisher FlowScanner valve diagnostic software, they analyzed the dynamic response of many of their critical valves. Based on their findings, […]
