A worksheet that calculates control valve installed gain can be part of any control valve selection process. For many years, the author has used, and promoted the use of, control valve installed flow ...

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.

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, ...

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.

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.
