Valmet ND9000 Intelligent Valve Controller, HART

Benchmark control performance on rotary and linear valves. Superior diagnostics and data storage capabilities. Local and remote configuration. Easy interpretation of diagnostics data. Efficient mounting program for all types of actuators, Low power consumption. Reliable and robust design. Hot swap support: possibility to install also on valves that are in process with 1-point calibration feature. SIL 2 approved device. Series 9000 valve controller with universal shaft and attachment face according to standard VDI/VDE 3845. Communication/Input Signal Range: 4–20 mA, HART (6 and 7) communication. Supply voltage 30 V DC. Load voltage: up to 9.7 V DC at 20 mA, corresponding to 485 O (maximum voltage drop). Local User Interface (LUI) functions: Local control of the valve, monitoring of valve position, target position, input signal, temperature, supply and actuator pressure difference. Guided-startup function. LUI may be locked remotely to prevent unauthorized access. Automatic/Manual linearization. 1-point calibration. Control configuration: aggressive, fast, optimum, stable, maximum stability. Configuration of the control valve - Rotation: valve rotation clockwise or counter-clockwise to close - Dead Angle - Low cut-off, cut-off safety range (default 2%) - Positioner fail action, open/close - Signal direction: Direct/reverse acting - Actuator type, double/single acting - Valve type, rotary/linear.
