A valve for metering fluids, for fuel injection valves for internal combustion engines, includes an electromagnetic actuator in a housing and a valve needle actuatable by an armature of the actuator, which actuates a valve closing body interacting with a valve-seat surface to form a sealing seat. The armature is movably guided on the valve needle. A stop element connected to the valve needle limits, with an actuation of the valve needle, a relative motion between the armature and the valve needle. The stop element includes at least one elastically deformable part and one stop piece, the elastically deformable part being shaped as a sleeve, and the stop element being configured so that the armature, upon the limitation of the relative motion between the armature and the valve needle, initially contacts the elastically deformable part and impacts the stop piece after a corresponding elastic deformation of the elastically deformable part.
