1. A latching assembly for a solenoid operated valve, the latching assembly comprising:
a solenoid assembly including a core defining a bore extending along an axis, and a coil mounted to the core and disposed about the axis; and
an armature assembly including an armature stud disposed at least partially within the bore and extending along the axis, an armature disc disposed radially about a portion of the armature stud and defining at least one window, at least one stationary magnet respectively disposed within the at least one window, and the at least one window extending away from non-polar sides of the at least one stationary magnet, such that for each window there is space between the window and each of the non-polar sides of the stationary magnet disposed within the window and nowhere does the window contact the non-polar sides of the stationary magnet disposed within the window.
