Valmet Me-sto Neles ND7000 Intelligent Digital Valve Controller with ASCO Solenoid Valve for Process Control
Product Overview
The Neles ND7000 intelligent valve controller is a versatile, high-performance digital positioner that operates on virtually any control valve actuator. Combining robust hardware with advanced diagnostics and open connectivity, it reduces total cost of ownership while delivering precise valve positioning and minimized process variability in demanding industrial environments.
Key Features
- Same unit for linear/rotary valves and single/double-acting actuators
- Low air consumption and energy-efficient design
- Local User Interface for real-time monitoring of position, pressures, temperature, and signal
- Remote configuration via DTM, EDD, or asset-management systems
- SIL 2 certified safety capability
- Vibration- and impact-tolerant construction with IP66 protection
- Optional arctic temperature range (–53 °C) and position transmitter
- Extensive hazardous-area certifications (ATEX, IECEx, etc.)
