There are many configurations of directional
control valve. Directional control valve has complex
construction, such as moving spool to control the direction of
actuator and desired speed. Magneto-rheological (MR) fluid is
one of controllable fluids. Utilizing the 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 presents the design of
multi configuration MR directional control valve. The
construction and the principle of work of the valve are
presented. The experiment was conducted to show the working
principle of the valve functionally. The valve worked
proportionally to control the direction and speed of hydraulic
actuator. The result demonstrated the operation of MR
directional valve in eight configurations. The MR directional
valve can replace many types of the spool directional control
valve for controlling hydraulic actuator.
