Abstract: FIELD: electrical engineering. 
     SUBSTANCE: invention relates to electrical engineering and can be used to control electromagnetic valves (EMV). The described result is achieved by the fact that the moment when the electromagnet armature begins to move is determined when the local maximum of the current is reached in the electromagnet winding of the valve upon actuation; the moment when the electromagnet armature reaches the end position upon release is determined when the local maximum of the current is reached in the electromagnet winding of the valve during release. The time of the activated state of the valve is therein defined as the time interval from the moment when the electromagnet armature begins to move upon actuation until the moment when the electromagnet armature reaches the end position upon release. The voltage is removed from the electromagnet winding to release the valve in two stages. First, after confirming that a local maximum of the current is reached in the electromagnet winding of the valve upon actuation, the winding is disconnected from the positive terminal of the power source, opening the upper switch and forming a circuit of slow recovery of the magnetic power of the electromagnet whereat this accumulated power is released as heat at the active resistance of this circuit. The electromagnet winding is then disconnected from the negative terminal of the power source, opening the lower switch and forming a circuit of fast recovery of magnetic power whereat this accumulated power is returned to the power source. For implementation of the proposed method, a functional chart of the apparatus and an electrical schematic diagram of the power stage thereof are proposed. The operating capacity and efficiency of the proposed technical solution are confirmed experimentally. 
     EFFECT: simplification, expanded operating capabilities, and increased power efficiency of controlling the EMV.
