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 ...
If you suddenly have the need for a two-way, flow control valve — from a valve-selection standpoint — what kind of questions do you ask yourself? Many, perhaps, don’t ask any questions and may make ...
"Hydraulic Control Valves" describes the three main types of control valves and their functions in a hydraulic system. Control valves control the direction, pressure, and flow rate of fluid as it ...
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.
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 ...
Figure 1. High-pressure district or campus steam is reduced to lower pressure for building use. The controller receives the low-pressure steam reading from the transmitter and regulates low-flow ...
Hydraulic Control Valves describes the three main types of control valves and their functions in a hydraulic system. Control valves control the direction, pressure, and flow rate of fluid as it moves ...
