Modern electric valve actuators offer far more than their simpler predecessors, and as a result they are seeing widespread adoption throughout the process industries. Advanced monitoring software provides early notice of developing problems as well as actionable suggestions, empowering maintenance teams to intervene and prevent production impacts.
A JHFoster.com article, What Are Pneumatic Actuators Used For? Types, Applications & Uses, highlights several of these applications.
Engineers who design safety systems are always mindful of a few basic truths: Anything can fail, so there should always be a backup. And sometimes, backups need backups. Looking at how this concept applies to pneumatically operated emergency shutdown (ESD) valves, and other similar on/off valves, is the main topic of Emerson’s Jeff Welch’s article in the November 2020 issue of Chemical Engineering.
