Valve Flow Control Optimization via Customization of an Intelligent Actuator

摘要

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.

1. A method of operating a valve actuator arrangement for a valve having a known flow profile, the method comprising:
receiving a first input control signal representing a first desired stem position based on a first desired flow profile, the first desired flow profile being different than the known flow profile, the first desired stem position having a corresponding first theoretical stem positional signal and a corresponding first theoretical flow rate; generating an actual first stem positional signal different than the first theoretical stem positional signal corresponding to an actual first stem position providing the first theoretical flow rate based on the known flow profile.
