Pneumatic Control Valve and New Stock Fishers Regulator and FLOWSERVE 3200MD 520MD 3800MD Valve Positioner
The Flowserve Logix 3200MD is a high-performance electro-pneumatic digital positioner that utilizes state-of-the-art piezo technology. It converts a standard 4-20 mA input signal with HART communication into precise pneumatic output for reliable valve positioning. Designed for both single- and double-acting actuators, it is suitable for linear and rotary valves and excels in demanding industrial environments.
- Piezo technology for superior response, reliability, and low air consumption.
- Local DIP switches and calibration buttons for straightforward on-site setup.
- Auto tuning with dynamic gain selection for optimized valve performance.
- Local status LEDs for quick visual indication of operation.
- HART 5 protocol for remote configuration and monitoring.
- Rugged aluminum or stainless steel housing with strong hazardous area certifications.
- Optional analog output board for position feedback.
