Description
Flowserve Logix 520MD Digital HART Valve Positioner
Product Overview

The Flowserve Logix 520MD is a digital HART positioner for pneumatic actuators that uses piezo technology for accurate and reliable valve positioning. It accepts a 4–20 mA input signal and supports HART communication for configuration and basic diagnostics. The positioner features local calibration via buttons and offers good performance in standard process applications with low air consumption and straightforward setup.
