Product Overview
The Neles ND9102HN Intelligent Digital Valve Positioner is designed for precise positioning and automated control of pneumatic valve actuators in industrial process systems. Part of the Neles ND9000 series, this intelligent valve controller uses a standard 4–20 mA electrical input signal with HART digital communication to regulate pneumatic output pressure and maintain accurate valve positioning. Its low-capacity spool valve is designed for smaller pneumatic actuators, supporting responsive valve movement, consistent flow regulation, and reliable performance in industrial automation applications.
Manufactured under the Neles brand, now part of Valmet, the ND9102HN features microprocessor-based control technology, contactless valve position measurement, and an IP66-rated enclosure suitable for demanding industrial environments. Its intelligent diagnostic capabilities support performance monitoring, automatic calibration, and convenient integration into distributed control systems. Compatible with single-acting and double-acting pneumatic actuators, the positioner supports both linear and rotary control valve applications. Related models include the Neles ND9103HXT/I02 and ND9102HXT, which feature different pneumatic capacities and optional feedback configurations.

How do I find the right part for my system?
Three options. Search by part number if you have the OEM code from Parker, Danfoss, Linde, Kawasaki, Kayaba or Grundfos — our search recognises both manufacturer codes and aftermarket cross-references. Browse by category if you know the component type (pumps, valves, cylinders, etc.). Or send a spec sheet to our engineering desk and we'll cross-reference against our 3,000+ SKU catalogue within one business day.
Can you help me size a pump or valve for my application?
Yes — sizing support is included with every order. Send us your operating pressure, flow rate, viscosity, drive speed and duty cycle, and our engineers will recommend a suitable component from our catalogue with full datasheets. We don't custom-build parts ourselves, but we can spec the right OEM component for almost any standard industrial application.
Can you cross-reference a discontinued part?
Yes — cross-referencing is one of the things we do most. Send us the original part number (even if the manufacturer has dropped it) and our engineering desk will identify a current equivalent or compatible alternative. Cross-reference lookups are free and typically come back within 4 business hours.
