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.

The piSAVE sense is a flow-control/check valve for suction cups. It works in any orientation, is dirt tolerant, and increases vacuum flow through the valve when vacuum level drops to compensate for ...

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 ...

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, ...

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

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 ...
