Pre-certified control valves have the potential to make installation and commissioning easier for end-users and system integrators. Emerson Process Management says it is the first control valve manufacturer to achieve independent third-party SIL 3 certification of four ranges of valves to IEC 61508 standards.

Such certification is expected to eliminate the need for prior use methodology while proving that the company’s design process, engineering, and testing comply with IEC 61508. Certification enables users to boost plant availability and safety by using Fisher GX, Vee-ball, easy-e and HP valves in safety instrumented systems (SIS) 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. 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 final control assembly, a component of the smart SIS complete safety loop offering, the company says.
