A solenoid valve for a brake system is provided to secure easy fabrication, and to reduce fabrication costs by simplifying composition. A solenoid valve for a brake system comprises a valve seat member(20), a sleeve(30), a valve core(50), an amateur(40), a recovery spring(45) and a filter member(70). The valve seat member includes an inside flow path(21) penetrated in a lengthwise direction, an outside flow path(22) formed on an outer surface in the lengthwise direction, and a seat part(23) having a first orifice(24) in the inside flow path. The sleeve includes a first end coupled to an outer surface of the valve seat member, and a flange part(31) fixed to a modulator block(100) of the first end. The valve core is coupled to a second end, which is opposite to the first end of the sleeve. The amateur is installed inside the sleeve so as to be moved back and forth, and opens/closes the first orifice. The recovery spring pressurizes the amateur toward the first orifice. The filter member is coupled outside the valve seat member for filtering foreign matters, includes a connecting flow path(73) connected to the inside flow path of the valve seat member, and is provided with a second orifice part(74) inside the connecting flow path. |
