- Abstract. usually, the rheological valves are working as a normally open valve. In this work, a rheological valve design is working as a normally closed (NC) valve. This feature is provided by the placement of a powerful permanent magnet that provides a magnetic field that impedes the movement of the smart MR fluids. Finite element modeling of this valve was carried out utilizing FEMM software, where the density of flux (B) and magnetic force (H) values were obtained stable along the effective gap. This valve operates at a variable flow rate based on the values of current applied to the coils. Where the relationship of current and flow rate is a linear relationship with increasing values of current, flow values increase. This design can be considered as an upgraded design of the rheological flow valves, which is characterized by great savings in wasted energy.
