Valve actuators drive the movement of valves either in on/off, modulating or control service. These actuators can be powered manually, pneumatically, hydraulically or electrically. For electric actuators, there is a great, educational YouTube series, Introduction to Valve Actuation and Electric Actuators.
A 4-minute YouTube video, Sempell Turbine Bypass Valves explains how these steam conditioning valves control steam with greater efficiency and accuracy. These valves include unique steam atomizing steam desuperheating nozzles, tailor made trims, and pressure balancing features to support a wide range of applications.
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.
Michelle Schulze shares how upstream oil and gas production sites must comply with limits on VOC emissions, and this effort is a good time to examine all the related equipment.
In a Flow Control article, The evolution of the butterfly valve, Emerson’s Joanne Lunsford describes some of the advances to for this important technology in manufacturing and production processes.
In a LinkedIn essay, Transform to Valve 4.0: Digital Control + Analytics, Emerson’s Jonas Berge describes how the performance of control valves can be more effectively managed and maintained for better operational 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...
This quick 3-minute video, Shafer RV Series Rotary Vane Valve Actuators– operating systems for critical pipeline applications illustrates the construction, features benefits and applications for these actuators.
In a Pumps&Systems article, Digitalization to Predict Reliability of Mechanical Valves, Emerson’s Riyaz Ali shares ways continuous monitoring technology can help.
The Fisher Control Valve Handbook is the best place to begin to better understand sizing and selection of control valves for your application.
In a Process Industry Informer article, Transform Operations with IIoT-enabled Control Valves, Emerson’s Clint Schneider and Michael Lester describe how actionable insights can by continuously monitoring the health of the vast array of control valves found in most process manufacturing and production operations.
In a Processing article, Monitoring pressure relief valves as part of a digital ecosystem reduces cost and improves performance, Emerson’s Marcio Donnangelo and Marcelo Dultra describe how continuous monitoring “can identify when pressure incidents happen while monitoring valve conditions to simplify maintenance programs.”
