Product Description

Product Description

Discover the FIELDVUE DVC6200 Series digital valve controller, an advanced valve-mounted, microprocessor-based instrument that infuses intelligence throughout the entire valve assembly. This state-of-the-art controller transforms a two-wire 4 to 20 mA control signal into a robust pneumatic output to effectively drive an actuator. It skillfully converts a standard two-wire 4 to 20 mA control signal into a precise pneumatic output, optimizing actuator performance for unparalleled precision.The versatile FIELDVUE instrument is equipped with multiple communication protocol options, including HART® 5 or 7, WirelessHART®, FOUNDATION™ fieldbus, or PROFIBUS, ensuring seamless integration and enhanced connectivity.

• Boasting an impressive array of certifications such as CSA, FM, ATEX, IECEx, CUTR, Lloyds Register, PESO, KGS, INMETRO, NEPSI, TIIS, Natural Gas Certified, and Single Seal Device, this controller ensures unmatched reliability and compliance.

• Designed to operate with either air or natural gas supply, ensuring flexibility in diverse operational environments.

• Its design allows for simple retrofitting in place of existing analog positioners on both Fisher and non-Fisher pneumatic actuators, making upgrades straightforward and cost-effective.

• Can be effortlessly mounted on any actuator or valve assembly, providing ultimate adaptability in various configurations.

• The commonality of parts across the FIELDVUE instrument series facilitates reduced spare parts inventory, optimizing maintenance efficiency.

 

Linkage‐Less Non‐Contact Position

Feedback - By utilizing a cutting-edge linkage-less

feedback system, depicted in the accompanying image,

physical contact between the valve stem and the

DVC6200 is expertly eliminated. This results in no

wearing of parts, thereby maximizing cycle life and

 

Built to Survive - The field-proven DVC6200 is engineered to withstand

harsh conditions with fully encapsulated electronics that

resist the damaging effects of vibration, temperature, and

corrosive atmospheres. Additionally, a weather-tight

wiring terminal box isolates field wiring connections,

safeguarding other areas of the instrument.

 

Actuator Overpressure Prevention

The DVC6200 digital valve controller is equipped with a comprehensive library of valve diagnostic alerts. These alerts, which can be conveniently accessed using an Emerson Field Communicator, provide prompt notifications of both current and potential equipment issues when integrated into a HART communicating system. It supports NAMUR NE107 alert categorization, delivering critical insights directly to your asset management system.

Alerts efficiently assist in the identification and notification of the following critical situations:

• Valve travel deviation due to excessive valve friction or galling, an issue that can be swiftly addressed before significant damage occurs.

• High cycle due to dither or improper tuning, allowing for immediate corrective action to preserve system efficiency.

• Total travel movement accumulation beyond a specified point, causing packing wear that can be proactively managed.

• Valve travel extending above or beyond a specified limit, signaling a need for immediate adjustment.

• Various instrument mechanical and electrical issues detected early, preventing costly downtime.

These invaluable alerts are stored in the DVC6200's onboard memory, ensuring that critical data is always at your fingertips.
