FIELD: monitoring and measuring equipment.
SUBSTANCE: invention relates to a control valve control system. Control valve control system comprises at least one sensor connected to valve shaft, detecting change in mechanical integrity of valve shaft and measuring voltage in localized zone of valve shaft. There is a device for obtaining data on this change in mechanical integrity of the valve shaft, which provides efficient servicing of the valve shaft. Said sensor can be a sound-radiating sensor, an active ultrasonic sensor or a sensor based on fiber-optic Bragg gratings (FBG).
EFFECT: control valve control system and method for detection of change in mechanical integrity of valve shaft.
