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 4C Health, Safety & Environmental conference, Emerson’s Derek Kelly highlighted ways to reduce fugitive emissions from tank venting equipment.
In a post, Valve Travel Control-Pressure Fallback, Emerson’s Riyaz Ali shared the process of how a control valve with a digital valve controller could fall back to standard pressure control upon an issue with the travel sensing mechanism.
A Digital Valve Controller, the DVC6200 (HART or Foundation Fieldbus) can detect position feedback problems and automatically revert to I/P [current to pressure] transducer mode to keep the valve operational. This avoids costly unplanned spurious trips, which are critical for plant operational performance.
In this very first episode of the EVALUE8 Podcast Series, we interview Karthik Dayalan, an expert and the Parts Business Development Manager in Emerson. Having met several customers, we discuss and explain the risk of using non-OEM parts and the benefits of using OEM Parts to operate your plant safely.
Marcelo Dultra, Process Industry Director at Emerson, recently published the Cover Story for the June 2021 issue of Valve World. The Cover Story describes how digital technology is being applied to pressure relief valves to reduce emissions, monitor performance, and save money.
In a recorded webinar, Smart Electric Valve Actuators for Critical Fail-Safe Applications, Emerson’s Knut Riegel and Umberto Bianchi share how these actuators are well-suited for emergency shutdown (ESD) applications.
In a Valve magazine article, Enhanced Safety in LNG Applications, Emerson’s Jean-Paul Boyer highlights the importance of pressure safety valves (PSVs) in maintaining safe operations as more of these LNG facilities come on-line across the globe.
Alek Duerksen’s Global Mining Review article, Making the Difficult Choices, describes the difficulties of tailing disposal and provides suggestions for choosing the proper automated isolation valves for this application.
Control valve response is a critical factor in successful control strategies and process variability. In a ControlGlobal.com article, Responsible control valve response, Emerson’s Greg McMillan and James Beall discussed the efforts underway to include valve responsiveness into the ISA 75.25 Control Valve Dynamic Testing standard.
In a recent Oil & Gas Engineering article, Next-gen trim cuts rotary valve cavitation, Emerson’s Brandon Bell describes how additive manufacturing, based on 3D printing technology advancements, enabled the development and manufacturing of anti-cavitation trim for rotary valves.
Emerson’s Roman Kudinov alerted me to a YouTube playlist of quick, less than 2-minute videos that show the capabilities of diagnostics, configuration and monitoring in the DCMlink Software for electric valve actuators. DCMlink collects data from electric actuators, provides connectivity to plant level asset management systems, helps users interpret performance data, assesses health condition of devices, and optimizes maintenance activities.
