The Fisher 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.

The DVC6200 is widely used across various industries where precision and uptime are critical:
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.
