Abstract: Degrees of abnormality of a valve and an actuator that drives the valve are estimated. An information processing system (100) according to the present invention includes an acquisition unit (110) configured to acquire angular velocity data of a rotation of a rotating shaft, the angular velocity data being detected by an angular velocity sensor, and an estimation unit (120) configured to estimate a degree of abnormality of each of an actuator (2) and a valve (3) by referring to the angular velocity data acquired by the acquisition unit (110).

Abstract: A valve state grasping system, a display device and a rotary valve, a valve state grasping program, a recording medium, and a valve state grasping method that enable efficient valve system monitoring and accumulation of information. The system includes a valve V, a sensor unit, a server including a database, a terminal device including a display unit, and a system control unit. The database includes a position information unit, a history information unit, and an inference information unit. The position information unit includes unique information and pipe attachment information, and the history information unit includes at least measurement information and diagnosis information. The system control unit accumulates information of the position information unit and information of the history information unit in association with each other and outputs predetermined inference information from the inference information unit based on information of the position information unit and information of the history information unit.
