A pressure relief system for detecting and abating an overpressure in a pressurized fluid. The system includes a pressure response assembly that has a pressure responsive member, such as a buckling pin, configured to buckle when a predetermined force is applied to the member. When the buckling pin buckles, a piston slides to expose an inlet to a communication path to an actuator assembly. The actuator assembly includes a pair of sliders that move from a retracted position to an extended position when pressurized fluid enters an actuator assembly housing. The sliders have a rack that turns a pinion when the sliders move from the retracted position to the extended position. The pinion is rigidly attached to a rotatable actuator shaft. Rotation of the actuator shaft causes a valve assembly to open or close to direct the pressurized fluid through an overpressure path.
