Tens of thousands of valves are required to manage the myriad of fluid and gasses in a power generation facility. Whether the valve is for isolation, flow reversal protection or something completely ...

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, ...

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 ...

Maintaining valves throughout a plant’s lifetime helps to preserve optimal performance, minimize supply disruptions and ...

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, ...
