The FIELDVUE DVC6200 Series digital valve controller is a valve-mounted, microprocessor based instrument that brings intelligence to the entire valve assembly,it converts a two‐wire 4 to 20 mA control signal into a pneumatic output to an actuator. The FIELDVUE instrument is available with either the HART® 5 or 7, WirelessHART®, FOUNDATION™ fieldbus, or PROFIBUS communication protocol.
• Certifications include: CSA, FM, ATEX, IECEx, CUTR, Lloyds Register, PESO, KGS, INMETRO, NEPSI, TIIS, Natural Gas Certified, Single Seal Device.
• Air or natural gas supply.
• Can easily be retrofitted in place of existing analog positioners on Fisher and non-Fisher pneumatic actuators.
• Can be mounted on any actuator or valve assembly.
• Commonality of parts across the FIELDVUE instrument helps you reduce spare parts inventory.
Linkage‐Less Non‐Contact Position
Feedback - The high performance, linkage-less
feedback system, shown in picture, eliminates
physical contact between the valve stem and the
DVC6200. There is no wearing of parts so cycle life
is maximized.
Built to Survive - The field proven DVC6200
has fully encapsulated electronics that resist the
effects of vibration, temperature, and corrosive
atmospheres. A weather‐tight wiring terminal box
isolates field wiring connections from other areas
of the instrument.
Actuator Overpressure Prevention
The DVC6200 digital valve controller provides a comprehensive library of valve diagnostic alerts. These alerts are easily accessed with an Emerson Field Communicator. When installed as part of a HART communicating system, the DVC6200 delivers prompt notification of current or potential equipment issues directly to the asset management system and supports NAMUR NE107 alert categorization.
Alerts assist in identification and notification of the following situations:
• Valve travel deviation due to excessive valve friction or galling
• High cycle due to dither or improper tuning
• Total travel movement accumulation beyond a specified point resulting in packing wear
• Valve travel above or beyond a specfied point
• Various instrument mechanical and electrical issues
These alerts are stored in memory on board the DVC6200.
