FIELD: mechanical engineering. SUBSTANCE: invention relates to valves with electromagnetic drives and it can be used as actuating device to bypass working media in hydraulic or air fuel systems. Proposed electromagnetic valve contains hermetically sealed housing with coaxially installed spring-loaded armature-shutoff member, coil whose lead outs are brought out through hole in coil end face and case, closing magnetic circuit. Valve is furnished additionally with sealed connector with elastic seals. Connector is made solid and internal with electrically insulated connecting pins and is arranged from side of lead outs of coil coaxially with coil between coil and housing or between coil and case. Slots are made in sealed connector in which elastic seals are fitted to seal coil between housing and connector and connector and case enclosing the coil and sealing connector over external surfaces. Connecting pins of sealed connector are connected at one side with coil lead outs, and at other side, with lead outs of electromagnetic valve.
