When selecting a valve pressure class, users often limit consideration to familiar ASME B16.34 Standard Classes, but awareness of lesser-known ASME classes can lead to significant cost, size, and weight reductions, especially for high-pressure weld end valves. My...
Anti-surge valves protect centrifugal compressors from potentially catastrophic damage, but they are typically grossly oversized for common operating conditions. My article in the December 2024 issue of Automation.com, titled “The Art of Compressor Anti-surge Valve...
There are three basic alert settings within all Fisher digital valve controllers that provide advanced notice of degrading performance, but those alerts must be enabled, configured and monitored — ideally by following the four-step program outlined in this article.
Valves are critical in many power industry applications such as boiler feedwater & recirculation, superheat attemperation, turbine bypass, and more. In this YouTube Fisher Valves & Instruments Power Industry Application Series, you can learn about the role...
