Marshalltown, IA - Emerson Process Management announced June 5th that its Fisher Fieldvue DVC6000 Series Digital Valve Controller has received certification from TÜV Rheinland (Cologne, Germany), an internationally-recognized inspection authority. TÜV certification allows industrial manufacturers worldwide to apply DVC6000 instruments to emergency-shutdown valves (ESD) in safety instrumented systems (SIS) in compliance with IEC 61508 standards.
Using a third-party authority the DVC6000 underwent product reliability analysis and testing including failure mode effect and diagnostic analysis (FMEDA). Results prove the product complies with international standards including IEC 61508 for functional safety and is suitable for use up to and including SIL3 applications.
The TÜV certification process is comprehensive and thorough and not only covers detailed FMEDA tests of every component of the Digital Valve Controller, but also evaluates Fisher's internal procedures and manufacturing competence to comply with IEC 61508 requirements.
Using the DVC6000 valve controller, users may conduct partial-stroke tests of the valve while the process is on-line. Simplified and secure testing procedures facilitate more frequent testing and continuous monitoring. Users may also improve their predictive maintenance through diagnostic capabilities, enabling them to detect valve problems early, before they become covert failures. Finally, DVC6000 users may time and date-stamp their valve-performance data to aid the documentation requirements of IEC 61508.
