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.

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, ...

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, ...

Control valves experience significant reaction loads when they regulate choked flow. The highly restrictive, complex flow path of existing severe-service valves dissipates the forces from ...

A new program from UGI aims to convince owners of older homes to install an inexpensive safety valve to prevent fires or explosions. It's called the excess flow valve. "It's a safety device that is ...

The EGV Series high-flow poppet valves are electronically piloted versions of the company’s GV Series valves. The EGV Series high-flow poppet valves are electronically piloted versions of the ...
