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 ...

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 ...

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 ...

Equipment designers find that proportional control technology is ideal where precise performance is required in variable pressure or flow applications. Often perceived as more complicated than other ...

In hydrogen refueling and distribution systems, reverse flow prevention is critical. Pressure imbalances or transient ...

A proportional solenoid valve is an electromagnetic valve designed to respond to a variable power input to regulate the flow of liquid and/or gas proportionately. It is used to control the flow rate ...
