Abstract	This paper presents a proportional pressure reducing valve for clutch control system and for tilting pad angle control of the hydraulic pump system. The proportional pressure reducing valve of this study has a spool with a reducing pressure control pin and a proportional solenoid actuator instead of an on-off solenoid actuator. The solenoid actuator consists of a bobbin with coils, a plunger and a core with a control cone. The control cone is a very important equipment for the attraction force adjustment and controls the flux saturation and the flux leakage. So the attraction force is constant in the range of the control cone. In this study, a new proportional reducing valve with a pressure control pin was proposed and the validity of the new mechanism with a pressure control pin was discussed. The dynamic characteristics of the object proportional pressure reducing valve were studied by numerical analysis using the mathematical model. Also, the static and the dynamic characteristics of the new pressure reducing valve were tested by testing system which is based on test standard.
