Abstract
A valve for an anti-lock brake system, wherein the anti-lock brake system is configured for controlling flow of a fluid, includes a housing defining a cavity therein and having a longitudinal axis, a valve seat disposed within the cavity so as to define a first passage for the fluid, and an armature disposed within the cavity so as to at least partially define a second passage for the fluid. The armature is translatable with respect to the valve seat along the longitudinal axis and matable with the valve seat to seal off fluid communication between the first passage and the second passage. The armature defines a surface that is substantially resistant to corrosion from the fluid, and the surface is substantially free from a coating including zinc.
