1. A pressure relief device for a system containing a pressurized fluid, comprising;

  • a main valve body including an axial passageway defining an inlet port, an outlet port, and a fluid flowpath between the inlet and outlet ports;

    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 connected to the valve plug;

    an activation component installed between the force transmission component and a mounting surface, the activation component configured to prevent axial movement of the valve until a predetermined pressure is exerted on the valve; and

    wherein the force transmission component only transfers an axial force acting on the valve plug to the activation component.
