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 […]
Data available in manufacturing and production facilities is growing faster than people can process. In a Process Industry Informer article, How Valve Condition Monitoring Reduces Plant Downtime, Emerson’s Fabrice Hoenig highlights this challenge: The vast amount of data that is generated about equipment condition and performance offers a great opportunity to engineers, but it can […]
As staff in process manufacturing and production facilities shrink due to economic or demographic conditions, on-site engineers, operations and maintenance personnel must increase their breadth of skills at the expense of skill depth. In a recent post, Monitoring Control Valves with Remote Expertise, we described how remote expertise could help augment local staff in the […]
An ARC Advisory group study highlighted that “The global process industry loses $20 billion, or five percent of annual production, due to unscheduled downtime and poor quality. ARC estimates that almost 80 percent of these losses are preventable…” Key components in controlling a process are the control valves, which directly touch the process. As such, […]
