A brake traction control valve (30) is disclosed. The brake traction control valve (30) includes a valve core (31), a shell (32), an armature (33), an exciting coil (34), a plunger (40), and a return spring (36). The valve core (31) has an inlet (31a) to allow inside and outside of the valve core (31) to communicate with each other, and a valve seat (35) provided with an orifice (35a) therein. The shell (32) having a dome plus cylinder shape is coupled to the valve core (31) to cover one end of the valve core (31). The armature (33) is placed in the shell (32) to move forward and backward. The exciting coil (34) is placed around the shell (32) to cause the armature (33) to move forward and backward. The plunger (40) is placed in the valve core (31) to move forward and backward to selectively open and close the orifice (35a) while moving forward and backward by the armature (33). The return spring (36) returns the plunger (40) and the armature (33) to open the orifice (35a). The plunger (40) includes a first body (50) brought into contact with the armature (32), a second body (60) connected to one end of the first body (50) to move forward and backward so as to selectively open and close the orifice (35a), and a relief spring (70) provided between the first and second bodies (50,60) so that the second body (60) is pushed. <IMAGE>
