A valve gate assembly with a eutectic implement configured to degrade in response to a force imparted along a non-parallel load path. The unique architecture employed for various embodiments ensures a non-parallel load path is employed in triggering the shift in position for a valve gate. This enhances the integrity of the eutectic implements such that a wider variety of valve gate assembly dimensions may be utilized. This, in turn, allows for such assemblies to be utilized with larger production line volumes without compromise to safety measures afforded by such safety valves.
