Emerson’s Katherine Bartels and Adam Harmon address the subject of control valve choked flow in liquid and gas applications in an International Society of Automation Intech article, Choked Flow in Control Valves.
At the Emerson Exchange Americas virtual series, Emerson’s Reid Youngdahl, Trevor Stoakes and Michael Wyatt show ways to visualize control valve noise and ways to reduce it.
In a Flow Control article, Understanding and solving control valve cavitation problems, Emerson’s Thirumalai Karthik (TK) Arasu opens highlighting the potential severity of cavitation.
In manufacturing processes with flowing fluids, control valves are among the most important equipment to keep the process operating smoothly and reliably. For those not experienced in their design and operation, AIChE's CEP magazine has a great article, Evaluate...
The Fisher Control Valve Handbook is the best place to begin to better understand sizing and selection of control valves for your application.
Let's end the week with a quick 3:21 YouTube video, Mobile Service Centers. These are part of valve, actuator & regulator lifecycle services available from Emerson. The mobile service centers bring certified repair and onsite service capabilities for small and...
Control valves are the workhorses of most processes. They touch the process fluids and often contend with many challenges—abrasive and corrosive fluids, high pressures and temperatures, and vibrations caused by piping and surrounding process equipment, to name a few....
If you're new to the process industries and have responsibilities including a safe, reliable and efficient production process, then you likely need to understand how control valves work. And, one of the best sources for learning is the Control Valve Handbook. For...
Let's end this short week for the United States of America's 4th of July Independence Day holiday with an educational video from Emerson's Fisher Valves & Instruments YouTube channel. The video, Control Valve Sizing Basics: What is Pressure Drop?, describes what...
New technologies usually become more broadly adopted as multiple suppliers adopt the technology and provide interoperability. Standards efforts help to define common requirements into a specification for suppliers to follow in their technology development programs....
According to Wikipedia, superheated steam is steam: …at a temperature higher than its vaporization (boiling) point at the absolute pressure where the temperature is measured. It has: …tremendous internal energy that can be used for kinetic reaction through mechanical...
Because they directly touch the process flow, control valves play a significant role in the stability, robustness and variability in the process. One bad-acting control valve can create large problems for safe and reliable operations. At last week's AIChE Spring...
