Control Valve Fluctuation: Why It Happens and How to Stop It
A fluctuating control valve can lead to unstable process control, poor product quality, increased equipment wear, and unnecessary energy losses. The root cause isn't always the valve itself—it could be incorrect PID tuning, valve stiction, actuator problems, positioner issues, or changing process conditions.
Identifying the real cause early helps improve control accuracy, reduce downtime, and extend the life of your control system.
Stable valves mean stable processes—and better plant performance.
