An electrically controlled hydraulic valve device of the self-lapping type including a self-lapping supply valve for supplying hydraulic operating pressure to vehicle brake apparatus at a degree controlled by a pilot valve, which, in turn, is mechanically operated by a solenoid for causing the supply valve to supply at maximum operating pressure when the solenoid is completely deenergized, and to effect zero operating pressure and complete release thereof when the solenoid is fully energized, the degree of said operating pressure between said zero and maximum pressures being infinitely variable inversely to the degree of energization of the solenoid.
