Product Overview
The Valmet Neles ND9103HNT Intelligent Digital Valve Positioner is designed for precise 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 control signal with HART communication to regulate pneumatic output pressure and maintain accurate valve positioning. Its intelligent control technology supports stable flow regulation, responsive actuator operation, and reliable industrial automation.
The ND9103HNT features a medium-capacity pneumatic spool valve for actuators with stroke volumes of 1–3 litres, an integrated two-wire analogue position transmitter, automatic calibration, and advanced valve diagnostics. Its standard aluminium enclosure provides IP66/NEMA 4X protection, while compatibility with single-acting and double-acting actuators supports installation on suitable linear and rotary control valves. The positioner is ideal for oil and gas, chemical processing, power generation, water treatment, and industrial manufacturing applications.

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.
