Flowserve Logix 3200MD Digital Positioner with ASCO Solenoid Valve for Precise Industrial Valve Control
The Flowserve Logix 3200MD is a two-wire, 4-20 mA digital valve positioner that provides precise stem positioning for both double-acting and single-acting actuators in linear or rotary configurations. Fully powered by the input signal, it supports HART protocol for bidirectional communication and is configurable via the local interface, ValveSight software, or HART handheld communicators. It employs a two-stage control algorithm (inner-loop spool control and outer-loop stem position control) with electronic characterization, eliminating mechanical cams.
- Local user interface with QUICK-CAL button, jog buttons, DIP switches, and status LEDs for configuration, calibration, and diagnostics without external tools.
- Auto-tune and adjustable gain settings for optimized response across actuator sizes.
- Soft limits, Minimum Position Cutoff (MPC), and custom 21-point characterization.
- Intrinsically safe, explosion-proof, and non-incendive certifications (ATEX, FM/CSA, IECEx, InMetro, etc.).
- Advanced diagnostics including friction, leak, supply pressure, and pilot relay monitoring (Advanced/Pro options).
- Low air consumption (<0.3 SCFM at 60 psi) with high capacity (12 SCFM at 60 psi).

Control of linear Mark One valves, standard and optional Valtek rotary valves, and NAMUR-compatible rotary actuators in process industries requiring precise positioning, diagnostic capability, and hazardous-area compliance.
How is calibration performed?
Use the local QUICK-CAL button (Auto or Jog mode) or ValveSight/HART 375.
What air quality is required?
ISA 7.0.01 (dew point ≥18 °F below ambient, particles ≤5 µm, oil ≤1 ppm).
Can it operate in digital command mode?
Yes; the 4-20 mA signal can be ignored in favor of HART digital setpoint.
What is the fail-safe behavior?
Determined by actuator tubing and spring; positioner diagnostics monitor ability to reach fail-safe.
