An electromagnetically actuable valve, in particular an injection valve for fuel injection systems of internal combustion engines is provided. The actuable valve has a throttling point that joins a core and a connector part to one another. An annular insert that supports the throttling point in a radial direction is provided. The use of the annular insert makes it possible to utilize the advantages of the design of a valve tube with the throttling point, and at the same time creates the stability necessary for high-pressure valves. The annular insert is made from electrically nonconductive material or configured with an interruption at at least one point and mounted in an electrically insulated fashion. This prevents eddy currents, which have a negative effect on switching times, in the annular insert. The annular insert is located at least partially within an influence region of a magnetic field of a magnet coil, in the presence of a changing magnetic field.
