Fi sher DVC6200 Digital Valve Controller with 67DFR Filter Regulator for Precise Pneumatic Control
The Fi sher FIELDVUE DVC6200 is a microprocessor-based digital valve controller designed for precise modulating control of pneumatic actuators. It converts a 4–20 mA control signal (or digital fieldbus commands) into a pneumatic output while providing two-way digital communication via HART 5/7, FOUNDATION Fieldbus, or PROFIBUS PA. The instrument features contactless magnetic Hall-effect position feedback, eliminating mechanical linkages and delivering high resolution, reliability, and advanced diagnostics.

Modulating control of throttling valves in chemical, refining, power, and process industries; safety instrumented systems (SIS); high-vibration environments; and installations requiring advanced diagnostics and predictive maintenance.
Q: Can the DVC6200 be used for on/off as well as modulating service?
A: Yes. Special configurations (DVC6200f with logic blocks or DVC6200 SIS) support on/off and partial-stroke testing.
Q: Is linkage-free feedback reliable in high-vibration service?
A: Yes. The magnetic array and Hall-effect sensor eliminate wear and provide stable feedback even under vibration.
Q: What diagnostic software is required?
A: ValveLink software or AMS Device Manager unlocks full Performance Diagnostics.
