Disclosed is a pressure control valve used in a clutch of an automatic transmission. The pressure control valve includes a valve body having a supply port, a control port and a discharge port therein; a first insert disposed inside the valve body, the first insert being formed with an inlet connected to the supply port and an outlet for discharging fluid supplied through the inlet; a ball disposed inside the first insert to open/close the outlet; a second insert coupled to the outlet side of the first insert, the second insert being formed with a first discharge hole connected to the control port and a second discharge hole connected to the discharge port; a rod movably provided to the valve body, the rod having one end extending toward the ball, the rod having a poppet formed in the middle thereof to open/close the second discharge hole; and a solenoid moving the rod. With the above structure, according to a current value applied on the solenoid, the outlet of the first insert and a second discharge hole of the second insert are opened and closed by use of the ball and the poppet, or the opening degree is adjusted, thereby effectively adjusting the pressure of the fluid discharged through the control port, and preventing unnecessary waste of the fluid.
