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 ...

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 ...

While the electrical control integration of a solenoid valve enables an automatic response to a temperature sensor’s signal, their compact size also enables a close fit within the confines of a cold ...

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 ...

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, ...

A new pressure-relief valve that protects sensitive components in fluidic systems against high-pressure peaks, and also ...
