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, ...

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 ...

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 ...

If you suddenly have the need for a two-way, flow control valve — from a valve-selection standpoint — what kind of questions do you ask yourself? Many, perhaps, don’t ask any questions and may make ...

FLUID POWER CONNECTORS & COMPONENTS ULTRA-MINIATURE PRESSURE COMPENSATED FLOW CONTROL VALVE WITH LOW FRICTION DIAPHRAGM, BESWICK ENGINEERING CO. INC. Some applications need flow control valves that ...

Microfluidic technology has developed greatly in recent years, enabling multiple analysis systems to be placed on a microfluidic chip. However, microfluidic large-scale integration of control elements ...

These graphs compare the pressure/flow characteristics of orifice and capillary restrictors. The characteristic impedance of an orifice restrictor does not vary linearly, so it will not always match ...
