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.
Features include
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 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.
