Fisher FIELDVUE DVC2000 Digital Valve Controller Positioner Smart
Valve Positioner Emerson Pneumatic Positioner
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 an
enclosed push button and liquid crystal display (LCD) interface.
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.
The high performance, linkage-less feedback system eliminates
physical contact between the valve stem and the positioner. There
is no wear of parts so cycle life is maximized. Additionally, the
elimination of levers and linkages reduces the number of mounting
parts and the mounting complexity. Positioner replacement and
maintenance is simplified because the feedback parts stay connected
to the actuator stem.
Designed to meet intrinsically safe and non-incendive requirements,
this instrument delivers scalable functionality and high
performance in a small package.

Features
- The linkage-less feedback system is easy to install. At its very
basic functionality, the DVC2000 digital valve controller has a
local user interface that will allow you to configure, calibrate,
and tune the instrument
- Years of control experience has brought this product line to a high
level of reliability and dependability.
- The two-stage positioner design provides a mechanical platform that
enables responsiveness to small input changes and tighter process
control.
- Tests can be performed to identify problems with the entire control
valve assembly using ValveLink™ software, which assists in
pinpointing problems without disrupting the process and before the
equipment fails.
- Available with an I/O Options Package which includes two integral
limit switches and a stem position transmitter.
- Features a compact size with multilingual liquid crystal display.
- Integral mounting is available on Fisher GX, and 657 and 667 size i
actuators.
