Introduction

The DVC2000 digital valve controller is a communicating, microprocessor-based current-to-pneumatic valve positioner. It is designed to replace standard pneumatic and electro-pneumatic valve positioners. In addition to the traditional function of converting an input current signal (4-20 mA) to a pneumatic output pressure, the DVC2000 digital valve controller communicates via a local display panel and/or via the HART protocol. An option is available which provides isolated circuitry for two (2) integrated limit switches (for open/close valve indication) and a valve position transmitter (for separate valve position feedback).

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.
