PROBLEM TO BE SOLVED: To estimate soundness of a valve by grasping a tendency of the occurrence of faults due to a secular deterioration of the valve before it. SOLUTION: A valve condition monitoring system includes a sensor which is provided on a valve rod or a yoke portion for measuring strain of the valve rod or the yoke portion generating at the time of opening or closing a valve, a communication module for transmitting measurement information of the sensor to a monitoring center server and the monitoring center server for processing the measurement information. The system measures the measurement information of the strain sensor at the time of opening or closing the valve normally or periodically, transmits it to the monitoring center server, and diagnoses valve condition in the monitoring center server based on the measurement information.
