Recently, Dual Clutch Transmission(DCT) with high efficient of the manual transmission and convenience of the automatic transmission has been researched and developed. DCT is divided into dry and wet depending on whether the oil is used or not. Wet DCT have to use hydraulic pressure to deliver the clutch’s large torque without loss. Therefore, It is necessary to develop a solenoid-type control valve capavle of high pressure control at level of 60bar. In this study, the effect of spool and flange geometry affecting leakage has been investigated using computational fluid analysis. Also, prototypes were fabricated to evaluate leakage according to clearance.
