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 ...

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, ...

LONG BEACH, Calif. - Pumps are responsible for a significant part of the world’s electrical energy consumption, but their impact can be by using variable-speed pump control, especially in hydronic ...

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.

Choked flow in control valves is a subject of serious concern for industrial users. The term is usually associated with destructive process conditions that can damage valve internals or expose ...

A proportional solenoid valve is an electromagnetic valve designed to respond to a variable power input to regulate the flow of liquid and/or gas proportionately. It is used to control the flow rate ...

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 ...

March 30, 2007 Over the last century of automobile development, we have seen an enormous range of valve actuation technologies, ranging from pushrod, through single then double overhead camshafts, ...

Optimizing any cooling plant for minimal energy consumption is a demanding science. In many cases, minimizing chiller plant energy consumption requires modifications to the plant design, including ...
