Product Description

Product Description

The innovative FIELDVUE DVC6200 Series digital valve controller is a sophisticated, valve-mounted, microprocessor-driven instrument that adds a layer of intelligence to the complete valve assembly. This state-of-the-art device seamlessly converts a simple two-wire 4 to 20 mA control signal into a precise pneumatic output directed to an actuator, ensuring optimal performance.Available with advanced communication protocols such as HART® 5 or 7, WirelessHART®, FOUNDATION™ fieldbus, or PROFIBUS, the FIELDVUE instrument offers unparalleled adaptability.

• Certifications include an array of renowned standards like CSA, FM, ATEX, IECEx, CUTR, Lloyds Register, PESO, KGS, INMETRO, NEPSI, TIIS, Natural Gas Certified, and Single Seal Device.

• Compatible with air or natural gas supply, catering to diverse operational environments.

• Effortlessly retrofitted in place of existing analog positioners on both Fisher and non-Fisher pneumatic actuators, it modernizes system capabilities.

• Versatile mounting on any actuator or valve assembly, providing unmatched flexibility in installation.

• The commonality of parts across the FIELDVUE range simplifies maintenance and reduces your spare parts inventory, resulting in cost efficiency.

 

Linkage‐Less Non‐Contact Position

Feedback - This high-performance, linkage-less

feedback system, as depicted in the accompanying image, revolutionizes control by eliminating

the physical contact between the valve stem and the

DVC6200. With no wearing parts, it ensures maximum cycle life and reliability.

is maximized.

 

Built to Survive - The robust DVC6200

boasts fully encapsulated electronics that effectively resist

the challenges posed by vibration, temperature fluctuations, and corrosive

atmospheres. Its weather‐tight wiring terminal box

safely isolates field wiring connections from sensitive areas

within the instrument, ensuring long-term dependability.

 

Actuator Overpressure Prevention

The DVC6200 digital valve controller offers an exhaustive library of valve diagnostic alerts, easily accessed via an Emerson Field Communicator. Integrated into a HART communication system, the DVC6200 provides immediate notifications of existing or potential equipment issues, directly interfacing with the asset management system and adhering to NAMUR NE107 alert categorization.

These alerts offer precise assistance in identifying and notifying the following situations:

• Valve travel deviation caused by excessive valve friction or galling.

• High cycle occurrences due to dither or improper tuning adjustments.

• Accumulation of total travel movement surpassing a specified point, leading to packing wear.

• Valve travel extending above or beyond a specified point, potentially affecting performance.

• Various mechanical and electrical discrepancies within the instrument.

These critical alerts are conveniently stored in the on-board memory of the DVC6200, ensuring swift access and comprehensive monitoring.
