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 ...

Compressible fluid flow through control valves will inevitably cause some form of flow-induced vibration in the fluid system. Identifying the type and cause of the vibration requires detective work.

Control valves are power-operated devices used to automatically modify fluid flow or rate pressure in a process system. The terms 'control valve' and 'throttling valve' are often used interchangeably ...
