A pressure relief device is disclosed for a system containing a pressurized fluid. The device includes a main valve body having inlet and outlet flow ports and a valve plug positioned to seal the flowpath of the pressurized fluid between the inlet port and the outlet port of main valve body. A force transmission component is connected to the valve plug and an activation component is installed between the force transmission component and a mounting surface. The activation component is configured to prevent axial movement of the valve plug until a predetermined pressure is exerted on the valve plug. The force transmission component more efficiently transfers the output force acting on the valve plug to the activation component.
