The FIELDVUE DVC6200 Series digital valve controller is a revolutionary valve-mounted instrument, equipped with a microprocessor that infuses the entire valve assembly with cutting-edge intelligence, ensuring unprecedented levels of efficiency. This advanced device adeptly transforms a two-wire 4 to 20 mA control signal into a precise pneumatic output, seamlessly directing it to an actuator for optimal performance.The FIELDVUE instrument offers versatile communication options, with choices including HART® 5 or 7, WirelessHART®, FOUNDATION™ fieldbus, or PROFIBUS protocols, catering to a broad array of industrial needs.
• Boasts extensive certifications: CSA, FM, ATEX, IECEx, CUTR, Lloyds Register, PESO, KGS, INMETRO, NEPSI, TIIS, Natural Gas Certified, and features a Single Seal Device.
• Operates efficiently with either air or natural gas supply, providing flexibility for different operational environments.
• Versatile retrofit capability allows it to replace existing analog positioners on Fisher and non-Fisher pneumatic actuators with remarkable ease.
• Offers the convenience of being mounted on any actuator or valve assembly, enhancing compatibility and adaptability across applications.
• The commonality of parts across the FIELDVUE instrument line reduces spare parts inventory, streamlining maintenance and cost-effectiveness.
Linkage‐Less Non‐Contact Position
Feedback - This state-of-the-art, high-performance linkage-less
feedback system eliminates the need for
physical contact between the valve stem and the
DVC6200, ensuring parts remain unworn and
maximizing the cycle life of the system.
Built to Survive - The DVC6200 is engineered to withstand
harsh conditions with fully encapsulated electronics that resist
vibration, temperature fluctuations, and corrosive
environments. A weather‐tight wiring terminal box
securely isolates field wiring connections, maintaining the
integrity of the instrument's other components.
Actuator Overpressure Prevention
The DVC6200 digital valve controller features an extensive library of valve diagnostic alerts. These intuitive alerts can be accessed effortlessly via an Emerson Field Communicator. In a HART communicating system, it ensures swift notification of current or potential equipment issues to the asset management system, aligning with NAMUR NE107 alert categorization.
Alerts facilitate the recognition and notification of a variety of situations, including:
• Valve travel deviation caused by excessive friction or galling
• High cycle occurrences due to dither or improper tuning adjustments
• Accumulation of total travel movement beyond a specified threshold, leading to packing wear
• Valve travel exceeding a predefined limit, indicating potential issues
• Various mechanical and electrical instrument concerns
These crucial alerts are stored on the DVC6200, ensuring quick reference and action.
