Like so many of the core technologies integral to automated industrial operations—such as motors, drives, and I/O—valves don’t always receive the attention they deserve in the automation arena.

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 ...

3D printing techniques enable quieter, higher performing designs for final control elements. Control valve noise is a problem in many plant environments. The sound is created by very high pressure ...

An oscillating control valve may appear to be the source of control instability and repair efforts are usually focused only there. When this fails to solve the issue, further investigation often ...
