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.

The VED03M direct-operated four-way proportional-control valves conform to NFPA D03 and ISO 4401 mounting standards. The valves control direction and flow rate based on the current supplied to the ...

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 ...

Heart valves allow blood to flow one way and prevent it from flowing in the wrong direction. The tricuspid valve controls blood flow between the right atrium and right ventricle. The bicuspid or ...

Ordinarily, if you want liquid to flow in only one direction through a pipe, that pipe needs to be equipped with a flap-type valve – which could fail. Now, however, scientists have created a new type ...
