Neles ND9000 Valve Positioner: An Intelligent Choice for Industrial Fluid Control
Product Introduction
The Neles ND9000 valve positioner, equipped with a 32 - bit ARM RISC microprocessor, accurately converts 4 - 20mA control signals into pneumatic signals to drive control valves. It uses a non - contact eddy - current sensor to monitor the valve stem position for precise positioning. Supporting multiple communication protocols like HART and Profibus - PA, it enables easy integration and remote control.

Features
- Intelligent Diagnosis: With multiple diagnostic functions, it collects over 20 parameters in real - time, generates a health index, and warns of potential faults in advance, achieving 92% predictive maintenance accuracy.
- Multi - protocol Compatibility: Supports various protocols, fitting different control systems to meet diverse industrial needs.
- User - friendly Design: Features a cover - free local interface, supports DCS configuration and calibration, and the installation kit is backward - compatible.
- Harsh Environment Adaptability: With IP66 protection and intrinsically safe/explosion - proof design, it has passed multiple explosion - proof certifications, ensuring stable operation in inflammable and explosive environments.
Applications
Widely used in chemical, oil & gas, power, water supply, and sewage treatment industries, it precisely controls fluid media, ensuring safe and efficient production.
