Product Description

Product Description

The FIELDVUE DVC6200 Series digital valve controller is a revolutionary, microprocessor-based instrument expertly mounted on valves. It infuses unmatched intelligence and efficiency into the entire valve assembly, significantly enhancing operational performance. This exceptional device transforms a simple, two-wire 4 to 20 mA control signal into a sleek pneumatic output that powers an actuator with remarkable precision.. FIELDVUE instruments offer versatility with choices of HART® 5 or 7, WirelessHART®, FOUNDATION™ fieldbus, or PROFIBUS communication protocols, ensuring seamless integration with varying systems.

• Comprehensive certifications encompass CSA, FM, ATEX, IECEx, CUTR, Lloyds Register, PESO, KGS, INMETRO, NEPSI, TIIS, and Natural Gas Certified, affirming its reliability and safety as a Single Seal Device.

• Compatible with air or natural gas supplies, providing adaptability for various applications.

• Easily retrofittable, this controller seamlessly replaces existing analog positioners on both Fisher and non-Fisher pneumatic actuators, offering modernization without complexity.

• Versatile in its mounting capabilities, the FIELDVUE can be installed on any actuator or valve assembly, underscoring its flexibility.

• The uniformity of parts across the FIELDVUE instruments allows for a reduction in spare parts inventory, optimizing resource management.

 

Linkage‐Less Non‐Contact Position

Feedback - Boasting high performance, the innovative linkage-less feedback system

eliminates unnecessary physical contact between the valve stem and the

DVC6200, thereby enhancing reliability.

This contact-free design ensures no wearing of parts, hence maximizing

cycle life and durability.

 

Built to Survive - The robust and field-proven DVC6200

features fully encapsulated electronics, designed to withstand

vibration, temperature fluctuations, and corrosive environments.

The weather-tight wiring terminal box offers added protection,

isolating field wiring connections from other sensitive areas

within the instrument to ensure uninterrupted performance.

 

Actuator Overpressure Prevention

The DVC6200 digital valve controller boasts a comprehensive library of valve diagnostic alerts. These vital alerts are easily accessible with an Emerson Field Communicator. When integrated into a HART communicating system, the DVC6200 ensures swift notification of current or potential equipment issues, directly interfacing with the asset management system while supporting NAMUR NE107 alert categorization.

Alerts assist in identifying and notifying about the following critical situations:

• Valve travel deviations due to excessive valve friction or galling, preventing potential failures.

• High cycle issues arising from dither or improper tuning, enabling preemptive maintenance.

• Total travel movement beyond a specified threshold, indicating packing wear and addressing it promptly.

• Valve travel exceeding specified points, ensuring maintainable performance.

• Various mechanical and electrical instrument issues are flagged early, minimizing downtime.

These insightful alerts are securely stored in the DVC6200's onboard memory, ensuring they are readily available for analysis and troubleshooting.
