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 ...

On/off valves are basically on/off switches for hydraulic systems. They are typically installed in applications where precise position or speed control is not required. Proportional valves adjust flow ...

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.

This file type includes high resolution graphics and schematics when applicable. Today’s manufacturers routinely demand exacting precision and split-second timing from their high-speed production ...

Identify the forces that act on closure components and actuators. Describe how these forces work in the positioning of closure components. Prepare equations required to determine an actuator (i.e.

Turbine bypass valves are one of the most difficult applications in a power plant. Keeping these valves operating efficiently and avoiding unexpected failures is critical for plant operation. When ...
