Compressible fluid flow through control valves will inevitably cause some form of flow-induced vibration in the fluid system. Identifying the type and cause of the vibration requires detective work.

Before selecting an engineered solution for any fluid control application, it is crucial to understand the unique application and overall value that each ball valve provides. Ball valves come in a ...

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 ...

If you suddenly have the need for a two-way, flow control valve — from a valve-selection standpoint — what kind of questions do you ask yourself? Many, perhaps, don’t ask any questions and may make ...

ISA recently published Fluid Mechanics of Control Valves: How Valves Control Your Process by Hans D. Baumann, Ph.D., PE — a world-renowned expert on control valve technology who is credited with more ...

Directional-control valves are vital in any pneumatic circuit, directing or blocking airflow to control the speed or sequence of operations. One method of classifying directional-control valves is by ...
