Product Overview
The Flowserve Logix 3200MD is a two-wire, 4-20 mA input digital valve positioner that uses advanced piezo technology for precise, responsive valve positioning. It supports both single- and double-acting actuators in linear or rotary configurations, powered entirely by the control signal. Local interface options make setup straightforward, while HART protocol enables remote communication and diagnostics.
Features
- State-of-the-art piezo valve control for fast response and high reliability.
- Local status LEDs for quick visual feedback.
- Local DIP switches and calibration buttons for on-site adjustments.
- Auto tuning with dynamic gain selection for optimized performance.
- Utilizes HART 5 protocol for configuration and monitoring.
- Simple calibration via local interface or HART handheld.
- Supports analog or digital command sources (0% closed, 100% open).
