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 ...

EVR Products announced today the enhancement of its industrial pinch valve lineup, reflecting continued investment in ...

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, ...

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 ...

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.

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 ...

The VFOF-LE-BAH features a pneumatically controlled one-way flow control valve, non-return stop valves, and manual exhaust. Common applications for the valve are adjusting or stopping cylinder ...

A single power plant uses hundreds of valves to control almost every aspect of its operation. Valves, in conjunction with a controlling actuator, are used for pollution control, feed water, cooling ...

Feedwater control valves play a critical role in boiler operation. One important parameter of their design is the pressure drop at the rated condition as well as off-design conditions. However, ...
