Abstract
An electromagnetically actuatable valve which serves to control a flow of fluid. The valve includes a valve housing and a core of ferromagnetic material, as well as an armature which actuates a valve element cooperating with a fixed valve seat. When the magnetic coil is excited, the armature is attracted toward a stop face on the valve housing and is in contact there with an effective zone on the armature. The armature and the valve housing are formed of low-carbon steel, and both the stop face and at least the outer effective zone of the armature are provided with wear-resistant surfaces. The wear-resistant surfaces may be attained by nickel plating or by nitration.
