A solenoid valve for power steering capable of hydraulic pulsation control is provided to reduce a difference between a right steering force and a left steering force by controlling detail movements of a spool. A solenoid valve for power steering capable of hydraulic pulsation control includes a plunger(21), an electromagnet, and a coil. The plunger is rotatably fixed inside a cover. The electromagnet and the coil are installed around the plunger. A rotary shaft(23) is formed in the center of the lower part of the plunger. A screw part is formed on the rotary shaft. A plurality of magnetic bodies is formed on an outer surface of a cylindrical body of the plunger in the longitudinal direction at predetermined intervals. A hole is formed on the upper part of a spool(25) to be engaged with the screw part formed on the rotary shaft of the plunger. A spool screw thread(26) is formed on the inner circumferential surface of the spool. The spool is supported by a spring to move up and down. An upper part of the spool is coupled to the rotary shaft of the plunger.
