Emerson Process Management has received SIL 3 certification of several ranges of its Fisher valves to IEC 61508 standards. Emerson is the first control valve manufacturer to have achieved this independent third-party certification, which eliminates the need for prior-use methodology while proving that Emersons design process, engineering and testing fully comply with IEC 61508.
A total of four control valve ranges have been certified by independent third-party safety professionals at Exida for on/off operation within a SIL 3 safety instrumented function. The valves can be packaged with the SIL 3-certified Fisher Fieldvue DVC6000 SIS digital valve controller that, according to the manufacturer, enhances the safety function and monitors the health of the entire final control assembly, which is a core component of Emersons smart SIS complete safety loop offering.
