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.
Valves, Actuators & Regulators
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.
I received a question from a very old post here on the blog, Credit for Partial Stroke Tests in Verification Process. The person was trying to get a better understanding about this chart showing how partial stroke tests (PSTs) can extend the intervals between full stroke tests for final elements in a safety instrumented function (SIF).
In an Oil & Gas article, Using NACE standards to protect against corrosion, Emerson’s Ali Babakr and David Macedonia describe ways to effectively comply with the standards to better address corrosion risks.
Many of these IIoT applications, whether powered by the Internet or internal intranets, have become more relevant as employees increasingly work from remote locations, requiring enhanced collaboration among widely dispersed personnel. An example is the remote monitoring of valves, along with collaborating for maintenance and repair, to improve reliability.
At the Emerson Exchange Americas virtual series, Emerson’s Mike Hoyme and Stanley Af demonstrated diagnostics in the final elements within a safety instrumented function.
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.
At the Emerson Exchange Americas virtual series, Emerson’s David Macedonia and Ali Babakr describes methods of protecting final control elements in corrosive applications.
At the Emerson Exchange Americas virtual series, Emerson’s Bryan Hodges, Jeff Gremillion and Luigi Bellan shared their expertise with ways to ensure safety in isolation valves used in cryogenic applications.
At the Emerson Exchange Americas virtual sessions, Emerson’s David Van Veen shared ways to improve operational performance with balance of plant valve optimization.
