Chinese Control Valve with Flowserve Logix 3200MD Digital Valve Positioner HART Smart Control
The Flowserve Logix 3200MD is a high-performance, two-wire 4-20 mA input digital valve positioner designed for precise control of both linear and rotary actuators. It features HART protocol for two-way remote communication and is fully powered by the control signal. Configurable via a local user interface with QUICK-CAL functionality, it supports single- and double-acting actuators in air-to-open or air-to-close configurations. Built for reliability in demanding industrial environments, it offers exceptional accuracy, low air consumption, and advanced diagnostic capabilities (available in Advanced/Pro models).
- Local interface with QUICK-CAL button, DIP switches, and LED status indicators for easy setup and calibration.
- Software-based characterization (Linear, Equal Percent, Custom) with soft limits and Minimum Position Cutoff (MPC).
- Two-stage control algorithm with inner-loop spool positioning and outer-loop stem feedback.
- Hazardous area certifications (ATEX, FM/CSA, IECEx, etc.) including intrinsically safe and explosion-proof options.
- Low air consumption (< 0.3 SCFM) and high capacity (12 SCFM).
- Optional pressure sensors for enhanced diagnostics and stability.
- Robust aluminum or stainless steel housing with IP65 protection.
