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.

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 ...

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 ...
