Product Description
Flowserve Logix 520MD Digital HART Valve Positioner
Product Overview
The Flowserve Logix 520MD is a digital HART positioner that uses piezo technology for accurate control of pneumatic actuators on linear and rotary valves. It accepts a standard 4–20 mA input signal and provides reliable positioning with local calibration via buttons. Many plants choose it for its low steady-state air consumption, straightforward setup, and solid performance in general process applications.
