A method for determining a projected remaining lifetime profile for a component of a valve, the method being characterized by : receiving, at an integrated diagnostics module , an identification of the component of the valve, wherein the component is capable of experiencing mechanical wear or fatigue, over time, during operation of the valve; receiving, at the integrated diagnostics module , an operating parameter corresponding to the component, wherein the mechanical wear or fatigue of the component varies with changes in the operating parameter; receiving, at the integrated diagnostics module , previously-recorded performance data of a reference component, where the previously-recorded performance data were collected during operation of the reference component under conditions experienced in a processing plant installation that are compatible with conditions under which the valve is to operate; developing, in a profiler of the integrated diagnostics module , the projected lifetime profile for the component based on the previously-recorded performance data and the operating parameter, wherein the projected lifetime profile indicates a projected lifetime of the component as a function of values of the operating parameter; receiving, at the integrated diagnostics module , current data of the operating parameter for the component during operation of the valve; analyzing, in a lifetime data analyzer, the current data of the operating parameter for the component and the projected lifetime profile for the component to determine a projected remaining lifetime for the component; and determining an operator notification state of the component based on the determined projected remaining lifetime. receiving, at an integrated diagnostics module , an identification of the component of the valve, wherein the component is capable of experiencing mechanical wear or fatigue, over time, during operation of the valve; receiving, at the integrated diagnostics module , an operating parameter corresponding to the component, wherein the mechanical wear or fatigue of the component varies with changes in the operating parameter; receiving, at the integrated diagnostics module , previously-recorded performance data of a reference component, where the previously-recorded performance data were collected during operation of the reference component under conditions experienced in a processing plant installation that are compatible with conditions under which the valve is to operate; developing, in a profiler of the integrated diagnostics module , the projected lifetime profile for the component based on the previously-recorded performance data and the operating parameter, wherein the projected lifetime profile indicates a projected lifetime of the component as a function of values of the operating parameter; receiving, at the integrated diagnostics module , current data of the operating parameter for the component during operation of the valve; analyzing, in a lifetime data analyzer, the current data of the operating parameter for the component and the projected lifetime profile for the component to determine a projected remaining lifetime for the component; and determining an operator notification state of the component based on the determined projected remaining lifetime. <EOS>
