Emerson DVC2000 Digital Valve Controller

The Emerson DVC2000 is a digital valve controller widely used in industrial process control for automating valve position management in applications such as oil and gas, chemical, power, and water treatment industries. The controller converts a standard 4-20 mA input signal into a precise pneumatic output that adjusts the valve actuator to regulate flow, pressure, or other process variables. Its use is essential where accurate valve positioning and reliable feedback are critical for maintaining optimized process performance and safety.

DVC2000

The Emerson DVC2000 features a compact design that mounts directly on valve actuators, supporting sliding-stem, quarter-turn, and other IEC/NAMUR-compliant actuator types. It utilizes a non-contact magnetic Hall-effect sensor for stem position feedback, eliminating mechanical linkages and reducing wear. This results in high reliability and reduced maintenance needs. The local user interface with a backlit LCD and push-button controls allows for straightforward configuration and diagnostics, supporting multiple languages for global usability.

The DVC2000’s pneumatic output pressure range is 0.5 to 7 bar, with the device capable of operating across a wide temperature range (-40°C to 80°C). It supports HART communication protocols, enabling integration with advanced asset management and control systems for remote diagnostics and parameter tuning. Its robust design meets hazardous area certifications such as ATEX and IECEx, making it suitable for use in explosive atmospheres.
