The FIELDVUE DVC2000 digital valve controller is simple to use, compact, and designed for easy
mounting. It converts a 4-20 mA input signal into a pneumatic output signal, which feeds the control valve actuator. Instrument setup is performed with a push button and liquid crystal display (LCD) interface. This interface is protected from the environment within a sealed enclosure. The interface supports multiple languages, available in two language pack options.
The DVC2000 uses a two-stage positioner design. The pre-amplifier stage provides high static gain for responsiveness to small changes in the input signal. The power amplifier stage delivers the right volume of air to the actuator, combining superior dynamic performance with minimal steady-state air consumption.
Available Mountings
Integral mounting to the Fisher GX Control Valve and Actuator System
Sliding-stem applications
Quarter-turn rotary applications
DVC2000 digital valve controllers can also be mounted on other actuators that comply with
IEC 60534-6-1, IEC 60534-6-2, VDI/VDE 3845 and NAMUR mounting standards.
Simplicity—The DVC2000 is easy to use. If you are mounting the instrument for the first time, the linkage-less feedback system is easy to install. Once a magnet array is assembled to the valve stem,positioner replacement is simple since there are no physically connected parts.
the DVC2000 instrument can be integrally mounted to the GX actuator, avoiding the
need for complicated mounting brackets. The positioner mounts directly to an interface pad on the actuator yoke leg with a secure 3-point mounting. Internal passages inside the actuator yoke legs route the pneumatic output of the digital valve controller to the actuator casing, eliminating the need for external tubing (only for the air-to-open configuration).
