Product Overview
The Valmet Neles ND9103HNT Intelligent Digital Valve Positioner is designed for accurate positioning and automated control of pneumatic valve actuators in industrial process systems. Manufactured by Valmet under the Neles brand, this ND9000 series positioner uses a 4–20 mA electrical input signal with HART communication to regulate pneumatic output pressure and maintain precise valve positioning. Its intelligent control system supports responsive actuator movement, stable flow regulation, and reliable industrial process automation.
The ND9103HNT features a medium-capacity pneumatic spool valve for actuators with stroke volumes of 1–3 litres, an integrated 4–20 mA position transmitter, automatic calibration, and advanced diagnostic capabilities. Its aluminium housing provides IP66/NEMA 4X enclosure protection, while its design supports compatible single-acting and double-acting pneumatic actuators. The positioner is suitable for oil and gas processing, chemical manufacturing, power generation, water treatment, pulp and paper production, and industrial valve automation.

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.
