Emerson Process Management has received SIL 3 certification to IEC 61508 standards for several ranges of its Fisher valves. Emerson is the first control valve manufacturer to have achieved this independent third-party certification, which eliminates the need for a prior use methodology. This certification enables users to boost plant availability and safety by using the Fisher GX, Vee-ball, easy-e and HP valves in safety-instrumented systems in up to SIL 3 loops. The four-control valve ranges have been certified by 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 enhances the safety function and monitors the health of the entire final control assembly, a core component of Emerson’s smart SIS complete safety loop offering. Emerson’s smart SIS provides an integrated approach to complete safety loops, from sensor to logic solver to final control element. The smart SIS solution enables customers to implement safer facilities, improve availability, lower lifecycle costs and ease regulatory compliance. The smart SIS system components include the Fisher-certified valves or SIL-PAC final control solution with Fieldvue DVC6000 SIS, plus Rosemount and Micro Motion certified and proven-in-use devices, the DeltaV SIS system and the AMS Suite: Intelligent Device Manager.
