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 is a poorly understood phenomenon that can affect control valve sizing, along with trim and material specification. This article was originally published in InTech's July/August issue.

Q: The control valve's actual operating conditions are compared with the design values. It's a 10-year-old equal-percent control valve. Installation and testing data is included in the accompanying ...

The piSAVE sense is a flow-control/check valve for suction cups. It works in any orientation, is dirt tolerant, and increases vacuum flow through the valve when vacuum level drops to compensate for ...

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 ...

A detailed understanding can pay off in greater process stability, lower valve wear and less waste of materials and energy. Stan: I've been an instrument engineer all of my professional life, and Greg ...

F low control valves control the movement or pressure of fluid. A valve is basically a mechanical device that blocks a tube or pipe either partially or completely to change the amount of fluid that ...

Pressure-compensated flow control valves are useful in a variety of hydraulic applications. For example, they benefit situations where it is necessary to maintain a constant speed of operation of a ...
