Abstract (en)
[origin: WO2013101097A1] A valve arrangement including a valve and a valve actuation arrangement is provided. The valve has a known flow profile. The valve includes a valve member and a valve stem operably coupled to the valve member for adjusting the position of the valve member. The valve actuation arrangement is operably coupled to the valve stem. The valve actuation arrangement includes a drive arrangement and a control arrangement. The drive arrangement is operably coupled to the valve stem and configured to adjust an actual stem position of the valve stem based on an actual stem positional signal. The control arrangement is configured to generate the actual stem positional signal. The control arrangement is configured to generate the actual stem positional signal based on an input control signal representing a desired stem position based on a desired flow profile being different than the known flow profile.
