A solenoid valve having particular utility in adaptive braking systems on automotive vehicles, in which the armature is provided with a conventional coil spring urging it toward its released position. A supplementary spring in the form of a bowed or wave washer whose free height is less than the total air gap of the valve also acts as an anti-residual magnetism shim. The supplementary spring makes it possible to minimize closing and opening times of the valve.
