The Flowserve Logix 3200MD is a high-performance, two-wire, 4-20 mA input digital valve positioner designed for precise control of linear and rotary actuators in industrial automation systems. As part of the Logix 3000 series, it combines advanced diagnostics, HART protocol compatibility, and robust construction to deliver reliability in demanding environments. This positioner is widely used in industries such as oil and gas, power generation, and chemical processing, where accurate valve positioning and remote communication are critical .
Key applications include:
Control of double-acting and single-acting actuators (no additional pneumatic amplifier required for double-acting setups).
Integration with HART-enabled systems for bidirectional communication.
Environments requiring compliance with explosion-proof (Ex) and intrinsic safety (IS) standards

3. Key Features & Functional Advantages
3.1 Advanced Diagnostics & Communication
HART Protocol Integration: Enables remote configuration, real-time monitoring, and predictive maintenance via HART-compatible handheld devices or software (e.g., ValveSight DTM)
Built-in Diagnostics: Detects valve stiction, actuator issues, and control loop anomalies, reducing downtime through proactive maintenance
3.2 User-Friendly Configuration
Local Interface:
DIP switches for quick setup (auto-tune/manual-tune modes, gain adjustment).
LED indicators for fault alerts and status updates.
One-Touch Calibration:
Automatic tuning completes calibration in <20 seconds.
Manual "jog mode" for valves without internal mechanical stops (e.g., using keys to position valves at 100% open)
3.3 Flexibility & Compatibility
Actuator Support: Compatible with both linear (e.g., sliding stem) and rotary (e.g., quarter-turn) actuators.
Analog Output Option: 4-20 mA position feedback for integration with legacy systems
Split-Range Capability: Supports up to 21 user-defined characterization curves for custom valve response
3.4 Robust Design for Harsh Conditions
Explosion-Proof Certification: Meets ATEX/IECEx standards for hazardous areas.

4.2 Calibration Procedure
Quick Calibration (Auto-Tune):
Press and hold the ACCEPT/QUICK-CAL button for 3 seconds.
The positioner closes the valve to set zero, then prompts the user to manually adjust to 100% open using keys.
Confirm with ACCEPT to complete calibration
Manual Calibration (Jog Mode):
Ideal for valves lacking mechanical stops.
Follow HART communicator prompts to define travel limits
