The upgraded Neles intelligent valve controller, ND9000, now incorporates a range of improvements that enhance its diagnostics and control performance, robustness and ease and efficiency of commissioning. The time to calibrate the ND9000 has been reduced by 30–75%, depending on the actuator volume. Improved usability is achieved by instant reaction to buttons and a running index showing the progress of the calibration run. When assembled on linear valves, linearization can be effectively performed using an easy, guided process. The firm’s iCV (intelligent control valves) with ND9000 valve controller help process plants to increase process efficiency, says the manufacturer. — Metso Automation, Oy, Helsinki, Finland
