Product Overview
The Neles ND9106HNT Intelligent Valve Positioner is a top-tier smart electro-pneumatic positioner manufactured by Valmet under the renowned Neles brand. Engineered for both rotary and linear pneumatic control valves, the ND9000 series positioner delivers precise dynamic control, benchmark operational reliability, and comprehensive online valve diagnostics. Operating on a two-wire 4 to 20 mA loop with full HART communication, the ND9106HNT ensures accurate valve stem modulation in the most demanding continuous process environments.
Built with an explosion-proof, flameproof, and intrinsically safe die-cast aluminium enclosure, this model is specifically engineered for classified hazardous areas. It features non-contact position sensing technology, eliminating physical mechanical linkages and sliding contacts to completely prevent wear, backlash, and measurement drift caused by pipeline vibration. Equipped with a high-flow pneumatic spool valve, local multilingual user interface with a graphical display, and integrated predictive diagnostics tracking valve travel, load, and pneumatic performance, the ND9106HNT is widely utilized across oil and gas refining, petrochemical facilities, pulp and paper plants, and power generation units.

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.
