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 ...

1. Flow-to-open cutaway. Control valves equipped with noise-abatement trim, such as a drilled-hole cage or a tortuous path stack, are typically oriented in the flow-to-open direction.

The distance between the seat and plug then changes to modulate the fluid flow. This makes for a high-capacity, precision-control valve suitable for high-pressure-drop, erosive flow that resists ...
