Fisherr FIELDVUEt DVC2000 Digital Valve

Controller

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.

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.
