A device for over-pressure protection of a tank has a main body defining a main passage with an inlet and an outlet. The main body also defines a release passage branched from the main passage. A shut-off mechanism is movably disposed within the main passage and defines an open position for allowing a liquid to flow from the inlet to the outlet and a closed position for at least partially blocking the flow. Additionally, a plunger is movably disposed within the main body and connects to the shut-off mechanism. The plunger has a weight sufficient to maintain the shut-off mechanism in the open position until pressure in the release passage exceeds a predetermined value.
