The ultraminiature PCFCD-1N1 pressure-compensated flow-control valve, with a low-friction diaphragm, is designed to maintain a constant flow rate, regardless of variations. The ultraminiature ...

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 ...

Instron’s pneumatic side-action grips feature an adjustable flow-control valve that can be used to slow down the closing speed and help prevent accidents.

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, ...

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 ...
