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.

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 ...

Fluid-handling devices are not basically concerned with the modulation of power, but only with the movement of fluid. Choosing a fluid-handling valve used to be easy, because each one had its own area ...

A single power plant uses hundreds of valves to control almost every aspect of its operation. Valves, in conjunction with a controlling actuator, are used for pollution control, feed water, cooling ...
