One of the main parts in a hydraulic system is the directional control valve, which is needed in order to operate an hydraulic actuator. The magneto-rheological (MR) valve has been proven can replace hydraulic directional control valve for controlling hydraulic actuator by few researcher in the form of Wheatstone bridge arrangement of four set of MR valve with no moving part. However, the arrangement is not compact in one unit. Generally, compact unit is more practical to be used in hydraulic system. Thus, a new design needs to be considered to produce compact unit. The main objectives of this present research are to design a MR directional control valve using MR fluid, to analyse its magnetic circuit using FEMM software, and to study and simulate the performance of this valve.
