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.

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 ...

Equipment designers find that proportional control technology is ideal where precise performance is required in variable pressure or flow applications. Often perceived as more complicated than other ...

An oscillating control valve may appear to be the source of control instability and repair efforts are usually focused only there. When this fails to solve the issue, further investigation often ...

A worksheet that calculates control valve installed gain can be part of any control valve selection process. For many years, the author has used, and promoted the use of, control valve installed flow ...

Like so many of the core technologies integral to automated industrial operations—such as motors, drives, and I/O—valves don’t always receive the attention they deserve in the automation arena.

Valves are essential elements for controlling fluid system performance. Virtually every fluid-power system requires some type of valve. In a hydraulic system, valves may control pressure, flow to an ...

Control valves, as the core components of flow control and pressure-regulating pipeline systems, critically influence operational safety and maintenance efficiency. Although cavitation induced by ...

Committee will create standards on face-to-face dimensions for the various types of control valves as defined in ANSI/ISA-75.05.01-2000 (R2005), Control Valve Terminology, with the exception of clamp ...

Classic Mustangs equipped with Bendix power-assisted steering yield all kinds of challenges for enthusiasts who have to live with them. When components are fresh and everything is installed properly, ...
