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, ...

Plant engineers at Eskom’s Majuba Power Station in South Africa have been continuously looking for ways to improve efficiency and reliability. The six-unit, 4,000-MW, supercritical coal-fired plant ...

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 ...

Equipment designers find that proportional control technology is ideal where precise performance is required in variable pressure or flow applications. Often perceived as more complicated than other ...

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 ...

Microfluidic technology has developed greatly in recent years, enabling multiple analysis systems to be placed on a microfluidic chip. However, microfluidic large-scale integration of control elements ...

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.

Understanding and reducing noise from control valves is an important consideration for process facilities, especially those close to residential areas. After years of working with this issue, the ...
