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, ...

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 ...

Food and beverage applications must meet a variety of process temperature and pressure control requirements to maintain the tight temperatures that ensure product quality and safety. Selecting the ...

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.

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 ...

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 ...

In a recent installment of the International Society of Automation’s “Ask the Automation Pros” series, Erik Cornelsen, ...

Scaling is one of the most frequently occurring problems in geothermal power plants and can prohibit the control of well flow if it builds in the well or wellhead. At HS Energy on the Reykjanes ...
