Abstract: FIELD: valves. 
     SUBSTANCE: invention relates to flow valves. Flow control method involves training for correction of average current in the valve, at that current supplied to the valve is controlled as follows: flow passes for the first time, output flow causes switching mechanism to return, flow passes again, and output flow causes switching mechanism to return again. Current values are recorded when flows pass through valve twice as maximum values of average current, deviation values are obtained for each of maximum values of average current and initial value of average current and curve of flow-current is corrected based on deviation value. Initial value of the average current in the first learning process is set by default, and the initial value of the average current in the next training process is the value of the average current in the valve on the flow-to-current curve. 
     EFFECT: ruling out variations of hardware on accuracy of flow control.
