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 ...

In process flow control, there are many factors affecting variability, but the greatest contributor is the control valve’s performance. Issues associated with control valves, such as dead band, ...

To define control valve inherent flow characterization and inherent rangeability, and to recommend allowable deviations from characterizations curves which are described mathematically or graphically.

In recent years, much discussion has centered on C v ratings (also known as capacity coefficients or flow factors) and whether or not American, European, and Japanese pneumatic-valve manufacturers ...

A series of solenoid-operated isolation valves can provide a chemically inert fluid path through a large orifice for a high flow rate. The 150L-Series is designed for use in analytical instrumentation ...
