Disclosed is a solenoid valve for a brake system. The solenoid valve comprises an armature disposed inside a sleeve to open and close an orifice formed in a seat by moving up and down along an axial direction together with a plunger; an elastic member for providing an elastic force to the armature; a magnet core accommodating the seat therein and providing a driving force to the armature in a direction opposite to the elastic force of the elastic member; a seal stopper coupled to a lower side of the magnet core so as to communicate with the orifice and having a slot on an outer circumferential surface thereof to allow the flow of a fluid through the slot; an outlet filter forming an outer flow passage with the seal stopper; an inlet filter coupled to a lower side of the seal stopper; a lip seal fitted between the seal stopper and the inlet filter and having an inclined protruding portion to allow only one-way flow of the fluid; an orifice flow passage opened and closed by the up and down movement of the armature; and a one-way flow passage formed to include a mesh portion of the outlet filter, a gap formed between a modulator block and the lip seal due to a deformation of the lip seal, and a mesh portion of the inlet filter, wherein the inlet filter includes a protruding portion inclined outwardly so as to have a chamber therein, and the lip seal is provided so that the inside thereof can be inserted into the chamber.
