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 ...

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 ...

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.

Tips process engineers can leverage to minimize the time spent selecting actuators for different applications while still maximizing the reliability and durability of valves and automation mechanisms.

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 ...

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.

studying control valve user requirements for dynamic performance of control valves defining of terms, performance categories, test methods and instrumentation, performance parameters, specification ...

They work in harsh environments, and they get little or no recognition. But their impact on power plant efficiency can be significant. Valves and actuators are critical in almost every aspect of power ...
