A valve with an electromagnetic actuator, in particular an injector for fuel injection systems of internal combustion engines, comprising a core inside an excitation coil, an armature, by means of which a valve flap interacting with the stationary seat of the valve is located, a connecting tubular part located downstream of the core, which partially surrounds the anchor in the radial direction, characterized in that the core (2) and the connecting part (10) are connected to each other with the formation of a direct magnetic conductivity, wherein a throttle (13) is formed with a coupling piece (10) integrally.  4. The valve according to one of claims 1 to 3, characterized in that the wall thickness of the throttle (13) is less than the thickness of the core wall (2) and the connecting part (10).  5. The valve according to claim 2 or 3, characterized in that the core (2) and the connecting part (10) are rigidly connected to each other outside the throttle (13).  6. The valve according to claim 3, characterized in that a nickel-iron alloy or pure nickel is used as the material for the connecting part (10) with a throttle (13).  7. The valve according to one of claims 1 to 3, characterized in that, depending on the material used, the wall thickness of the throttle (13) is from 0.2 to 0.5 mm.  8. The valve according to one of claims 1 to 3, characterized in that the magnetic throttle (13) is made in the zone of axial extension of the armature (17).  9. The valve according to one of claims 1 to 3, characterized in that the armature (17) for axial orientation has at least one guide surface (36), and at least one guide surface is located so that it is in the zone axial extent of the throttle (13) and thereby completely surrounded by the throttle (13) in the radial direction.  10.
