Fi sher FIELDVUE DVC6200 Digital Valve Positioner Double Acting with Feedback Industrial Automation
The Fi sher FIELDVUE DVC6200 is a premier digital valve controller designed to provide high-precision control, diagnostics, and reliability for critical control valves. This specific version is a Double Acting configuration equipped with Position Feedback non-contact feedback technology. By eliminating mechanical linkages, the DVC6200 reduces wear and tear caused by vibration, significantly extending the service life and performance of the valve assembly in harsh industrial environments.
- Linkage-less Non-Contact Feedback: Uses a hall-effect magnet array to sense valve position. No touching parts means no wear, making it ideal for high-vibration and corrosive applications.
- High-Precision Control: Delivers fast response and accurate positioning for double-acting actuators, ensuring optimal process stability.
- Integral Position Feedback: Provides a 4-20mA signal back to the control system for real-time verification of the actual valve position.
- Advanced Diagnostics: Supports HART® communication, allowing for online performance monitoring and predictive maintenance to prevent unplanned shutdowns.
- Modular Design: Features a field-replaceable terminal box and pneumatic relay, simplifying maintenance and reducing spare parts inventory.
- Rugged Construction: Built for the toughest environments with a corrosion-resistant housing and encapsulated electronics.

The DVC6200 is widely used across various industries where precision and uptime are critical:
- Oil & Gas: Refineries, offshore platforms, and natural gas processing.
- Chemical/Petrochemical: High-vibration piping and corrosive reactors.
- Power Generation: Steam turbine control and feedwater systems.
- Water & Wastewater: Large-scale flow control and treatment facilities.
- Pulp & Paper: Precise control for stock lines and chemical dosing.
A: Conventional positioners use mechanical levers and springs that wear out or loosen over time, especially with vibration. The DVC6200 uses magnets, so there is no physical contact between the valve stem and the positioner, eliminating mechanical failure points.
A: Yes. The DVC6200 is designed for universal mounting and can be easily configured for either rotary (up to 90 degrees) or sliding-stem (up to 24 inches) applications.
A: Absolutely. Using HART communication, operators can run "In-Service" diagnostics to check valve health without interrupting the process.
A: No. This version includes an integrated 4-20mA feedback module, which provides the transmitter function internally.
