SYSTEM AND METHOD FOR PERFORMING VALVE DIAGNOSTICS

摘要

A method for performing diagnostics for a valve assembly includes obtaining valve assembly information including a set of data points where each data point of the set of data points includes a position of an actuator stem. The method includes classifying each data point of the set of data points as at least one of a plurality of data point types where the plurality of data point types includes a first data point type and a second data point type. The method also includes determining at least one valve assembly characteristic based on the classification of each data point of the set of data points where determining the at least one valve assembly characteristic includes measuring the position of the actuator stem at a specific point in time.
