Directional control valve is the main part in hydraulic system which has complex construction, such as moving spool to control the direction of actuator for required speed. Utilizing MR fluid properties, direct interface can be realized between magnetic field and fluid power without the need for moving parts like spool in directional control valves. This paper dedicates the experimental test of four ways, three position MR directional control valve. The experimental methods were done by connecting the MR directional control valve with hydraulic actuators. The experiment was conducted to show the principle work of the valve functionally and performance test for valve was done. The valve works proportionally to control the direction and speed of hydraulic actuators. As a result, the experimental result demonstrates the operation of MR directional control valve using two configurations. The experimental about ON-OFF and proportional operations is discussed. The MR directional control valve can replace many types of the spool directional control valve for controlling hydraulic actuator.
