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 instance, if you need to learn about globe valves, section 3.1.1 of the […]
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 this is, how to calculate it, and its importance in the selection of the […]
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. Today, industries such as warehouses, airlines and others employ radio-frequency identification (RFID) technology for increased productivity. The use of RFID […]
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 expansion against turbine blades and reciprocating pistons, that produces rotary motion of a shaft. The value […]
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 Meeting, Emerson’s James Beall presented Specifying Control Valve Performance to Achieve Desired Process Performance. In […]
