Overview

The DVC6200 digital valve controller mounts directly on Fisher actuators and receives a 4-20 mA control signal from the DCS or controller. Using advanced algorithms, it precisely positions the valve stem or shaft, compensating for friction and process variations. The integrated HART modem allows two-way digital communication, enabling users to access real-time data, perform diagnostics, and adjust parameters remotely via a handheld communicator or AMS Suite software. The device also stores historical data for trend analysis.

Applications

The DVC6200 is used in refining, chemical, power, oil & gas, and pulp & paper industries to control critical valves. Its diagnostic capabilities help detect developing problems such as sticking valves, actuator leakage, or instrument drift, enabling predictive maintenance and avoiding unplanned shutdowns. It is suitable for both linear and rotary control valves.
