EN An electromagnetic valve for control of flow of electrically non-conductive liquids is proposed and modeled. The device contains only one movable part (a cylindrical plunger) whose movement is controlled by a secondary magnetic circuit with a high-parameter permanent magnet and current in the field coil. The paper presents its mathematical model that is solved numerically. For computations we used our own code Agros2D based on a fully adaptive higher-order finite element method. The static characteristics of the device are calculated using a modified version of the Eggshell method in order to avoid undesirable peaks and oscillations. The principal results are evaluated and discussed.
