The electromagnetically operable valve has the an axially moveable valve needle which is formed from an armature, a valve-closure member and a connecting part connecting the two parts. The tubular connecting part has an elongated slit which, because of widenings of the starting sheet-metal part, has a smaller opening width at the end facing the valve-closure member than over its remaining axial extension. Thus, the valve-closure member can be attached very securely at the lower end of the connecting part by a welded seam, avoiding disadvantageous sink marks. The valve is suitable to be used in fuel-injection.
