    Control Valve Suitability in Safety Applications

    Sometimes an email exchange turns up something developed years ago that still has great value. So is this case with an article I received as an attachment on final control elements and their suitability in safety instrumented functions (SIFs) , a.k.a. safety loops. The article, When SIL suitability is required for final control elements , was written by Emerson’s Riyaz Ali back in 2011 for EngineerIT magazine...
