SIL 3 certification

Certification simplifies safety standard compliance for customers

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. 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 that enhances the safety function and monitors the health of the entire final control assembly, a core component of Emersons smart SIS complete safety loop offering.

Many process plants already rely on Fisher control valves from Emerson for reliable and consistent performance in process control. The extensive experience of end-users with Fisher valves bear testimony to their quality and reliability in general service applications as well as in more demanding severe service applications. This is important because, when designing SIS functions, choosing the right control valve is the first pre-requisite. Only Fisher control valves offer the combined benefits of proven process control excellence and safety-certification to IEC 61508.

Fisher valves are components of Emersons smart SIS safety management solution, an extension of the companys PlantWeb digital plant architecture. Emersons 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 life-cycle 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.
