In process flow control, there are many factors affecting variability, but the greatest contributor is the control valve’s performance. Issues associated with control valves, such as dead band, ...

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.

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 ...

Cavitation is the implosion of tiny vapor bubbles in a liquid when the static pressure reaches the vapor pressure of the specific liquid. This happens when, due to a high pressure differential across ...

Flow is controlled by either throttling or diverting it. Flow is controlled by either throttling or diverting it. Throttling involves reducing orifice size until all of the flow cannot pass through ...

Modular load-sensing valves control flow and pressure, permitting simpler, more-versatile hydraulics. It's no secret that OEMs want hydraulic controls that simplify mobile-equipment design and are ...

Feedwater control valves play a critical role in boiler operation. One important parameter of their design is the pressure drop at the rated condition as well as off-design conditions. However, ...
