Disclosed is a valve block for a hydraulic brake system. According to embodiments of the present invention, the valve block for the hydraulic brake system comprises: a first valve line in which NO valve accommodation bores are placed to respectively accommodate each of a large number of NO valves; a second valve line in which NC valve accommodation bores are placed to respectively accommodate each of a large number of NC valves; a pair of pump accommodation bores formed on both side surfaces to be symmetrical to each other and placed between the first and the second valve lines to accommodate a piston pump; a pair of first damping bores formed on both side surfaces to be symmetrical to each other and placed on an upper side of the first valve line to accommodate a first pulsation reducing apparatus; a pair of second damping bores formed on an upper surface to be symmetrical to each other and placed on an upper side of the first damping bores to accommodate a second pulsation reducing apparatus; a pair of low-pressure accumulator accommodation bores formed on a lower surface to be symmetrical to each other; and a pressure sensor accommodation bore formed on a front surface and placed adjacent to the pair of low-pressure accumulator accommodation bores, and may be provided by further comprising a first hydraulic line which connects in a straight line a discharge side of the pump accommodation bores, an inflow side of the first damping bores, a discharge side of the first damping bores, and a floor surface of the second damping bores to transport hydraulic pressure. The present invention aims to provide the valve block for the hydraulic brake system, which is capable of realizing the same flow path even when a damping apparatus is additionally installed for reducing pressure pulsation generated by pressure discharged from a pump.
