Mass Flow ONLINE B.V., the e-commerce channel of Netherlands-based Bronkhorst High-Tech B.V, has released a new series of pressure compensated control valves. The FLOW-CONTROL series, designed by ...

The UK-based company says it is designed to give pressure compensated flow control for flows up to 28L/min, working at 210 bar. The valve is said to have a hysterisis of better than 4% with PWM at a ...

Flow is controlled by either throttling or diverting it. Throttling involves reducing orifice size until all of the flow cannot pass through the orifice; bypassing involves routing part of the flow ...

Abstract: This paper presents an in-depth modeling of a pressure-compensated flow control valve (PC valve) by making its physical meaning more understandable and analysable. Proper simplification is ...

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 ...

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, ...

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, ...
