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.

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 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 ...

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 ...

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 ...

Understanding and reducing noise from control valves is an important consideration for process facilities, especially those close to residential areas. After years of working with this issue, the ...

At the Productonica China 2026 exhibition—a premier barometer for the future of smart manufacturing—the spotlight has moved decisively toward low-voltage DC servo technology. For international buyers ...

Microfluidic technology has developed greatly in recent years, enabling multiple analysis systems to be placed on a microfluidic chip. However, microfluidic large-scale integration of control elements ...
