Metso introduces upgraded Neles ND9000 intelligent valve controller

HELSINKI, Nov. 25, 2010 (Press Release) -

Metso has announced an upgrade of the Neles intelligent valve controller, ND9000, which now incorporates a range of improvements that enhance its market-leading diagnostics and control performance, robustness and the ease and efficiency of commissioning. The field-proven ND9000 was first released in 2003 enabling customers to use predictive diagnostics.

Improved commissioning

Commissioning has always been one of the ND9000's built-in benefits. Easy installation, guided quick start-up and automatic calibration as well as a local user interface on any valve have always been standard features of the ND9000 already on the design board.

The most significant improvements, which have been included without compromising any of the existing features, include: Faster calibration, improved usability, linearization, and enhanced commissioning.

- Calibration time of the new ND9000 has been reduced by 30 - 75%, depending on the actuator volume;

- Improved usability: Instant reaction to buttons, and a running index showing the progress of the calibration run;

- User-definable linearization. When assembled on linear valves, linearization can be effectively carried out using an easy, guided process.

In addition, improvements to the robustness of the ND9000 have been boosted to meet the most demanding field conditions.

Reducing life cycle costs

Metso's iCV (Intelligent Control Valves) with ND9000 valve controller help process plants to increase process efficiency by means of control valve constructions that provide superior performance, reliability and control accuracy. The new fast calibration capabilities of the ND9000 will reduce the commissioning time during start-up and maintenance which, together with unique online performance diagnostics and predictive maintenance features, will reduce life cycle costs.
