A sealing element of a valve, e.g., a gas valve, for controlling a medium includes a base body having a sealing surface, the sealing surface either (i) being inclined in relation to a center axis of the sealing element or (ii) having at least one inclined area. In addition, a valve seat support of the valve for controlling a medium includes: a first ring-shaped valve seat in a first valve seat plane; a second ring-shaped valve seat in a second valve seat plane; and a passage aperture situated between the first valve seat and the second valve seat, the first and second valve seat planes being perpendicular to a center axis of the valve seat support.

A fuel injector for fuel-injection systems of internal combustion engines. The valve includes an electromagnetic actuating element having a solenoid coil, a fixed core, an outer magnetic-circuit component and a movable armature to actuate a valve-closure member which cooperates with a valve-seat surface provided on a valve-seat member. The valve is characterized by its extremely small outside dimensions. The entire axially movable valve needle, including armature and valve-closure member, has a mass of only m&#x3c;=0.8 g. The valve is suitable as a fuel injector, especially for use in fuel-injection systems of mixture-compressing internal combustion engines with externally supplied ignition.
