VALMET ND9406 Stainless Steel High Capacity Intelligent Valve Controller
The VALMET / Neles ND9406 is a high-capacity intelligent valve controller from the ND9000 series, developed for demanding industrial process automation and pneumatic valve positioning. The ND9406 product family combines advanced valve control, digital communication and diagnostic capabilities with durable stainless steel housing construction.
Designed for compatible pneumatic actuators requiring high air-flow capacity, the ND9406 uses the high-capacity 06 pneumatic configuration. It is particularly relevant for applications with actuator stroke volumes greater than 3 dm³, subject to final actuator sizing and installation requirements.
The ND9406 series is available in three communication versions: ND9406H with HART, ND9406F with FOUNDATION Fieldbus, and ND9406P with PROFIBUS PA. Therefore, plant engineers can select the appropriate configuration according to their installed distributed control system and field instrumentation network.
Furthermore, the ND94 platform features stainless steel housing construction with a polymer composite cover. The intelligent ND9000 architecture also provides device and valve diagnostic information through compatible configuration and maintenance systems.
The available ordering codes include 20 variations across the HART, FOUNDATION Fieldbus and PROFIBUS PA families. Each complete ordering code should be verified for its communication protocol, approval options, accessories and actuator compatibility before purchase.
Key Features of VALMET ND9406
- High Pneumatic Capacity: Designed for compatible actuators with stroke volumes greater than 3 dm³.
- Three Communication Protocols: HART, FOUNDATION Fieldbus and PROFIBUS PA.
- Stainless Steel Housing: Durable housing with a polymer composite cover.
- Intelligent Valve Positioning: Supports accurate control of compatible pneumatic valve assemblies.
