Learning about Control Valve Performance
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...
Sizing Control Valves for Intended Applications
The Fisher Control Valve Handbook is the best place to begin to better understand sizing and selection of control valves for your application.
Valve and PRV Mobile Service Centers
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...
Assuring Control Valve Quality
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....
Globe Valve Basics
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...
Pressure Drop across Control Valves
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...
Advancing RFID-Based Productivity in Process Manufacturing
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....
Sizing and Selecting Control Valves for Desuperheaters
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...
Avoid Operational Issues with Proper Control Valve Selection
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...
What are Valve I/P Transducers?
As we continue to see a generational shift in the manufacturing industries, I like to highlight educational videos developed across the Emerson business groups. Our group managing Fisher Valves & Instruments products has recently posted a 2:51 YouTube video, What...
Solving Control Valve Vibration Challenges
The production areas of many process manufacturing facilities can sometimes seem deafening. Some of this noise may be attributed to excessive vibration surround equipment such as control valves, piping and instrumentation. Emerson's Adin Mann and Shawn Anderson have...
