Directional-control valves are vital in any pneumatic circuit, directing or blocking airflow to control the speed or sequence of operations. One method of classifying directional-control valves is by ...

Learning the basics can ease loop tuning frustration and ensure stability. During plant operations, it seems that tuning control loops is an ongoing task, which can be a continual frustration to ...

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.

In most bulk powder handling applications, slide gates are predominantly used to either completely shut off or completely open the flow of material. In some instances, it may become necessary to limit ...

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 ...

Reliable flow control equipment plays an essential part in the control of many manufacturing and industrial processes. Control Engineering Europe takes a closer look. When managing a liquid, gas or ...

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 ...

Many engineers may wonder if it is possible to have flashing liquid flow in a control valve even if flow is not choked. The short answer is yes, but it is not very common. This article provides a more ...
