Proportional valve for gaseous and fluid medium, has head comprising outer core and inner core that includes conically tapered end part, where part is immersed into conical recess of axially displaceable armature arranged in chamber

The valve has a magnetic head (2) comprising an electrical coil (4), an outer core (12) and an inner core (11) that includes a conically tapered end part (17). The part is immersed into a conical recess of an axially displaceable armature (30), where the armature is arranged in a valve chamber (27) and includes base and cover disks (31, 32) connected with one another. A non-magnetizable disk (13) is arranged at a side of the coil and pressed between the inner and outer cores in a hermetically sealed manner, and the armature has a sealing body (33) that is pressed against a valve seat (18). Das Ventil ist für gasförmige und flüssige Medien vorgesehen und umfasst einen Magnetkopf mit einem Außenkern und einem Innenkern, der mit einem kegelstumpfförmigen Endteil in eine trichterförmige Ausnehmung eines axial verlagerbaren Ankers eingreift.
