Emerson Process Management earned SIL 3 certification of several ranges of its Fisher valves to IEC 61508 standards. The independent third-party certification proves that Emerson’s design process, engineering, and testing fully comply with IEC 61508. This certification enables users to boost plant availability and safety by using the technology-leading Fisher GX, Vee-ball, easy-e, and HP valves in safety instrumented systems in up to SIL 3 loops, per IEC 61508. The four control valve ranges have been certified by independent third-party safety professionals EXIDA for on-off operation within a SIL 3 safety instrumented function. The valves can be packaged with the already successful SIL 3-certified Fisher FIELDVUE DVC6000 SIS digital valve controller to enhance the safety function and monitor the health of the entire final control assembly, a core component of Emerson’s smart SIS complete safety loop offering.
