A pressure relief valve is provided including a flapper pivotally mounted to a housing. The flapper is movable between a first position and a second position. A protrusion extends from a first surface of the flapper. A biasing mechanism is positioned near a first end of the flapper. The biasing mechanism is configured to apply a biasing force to the first surface of the flapper. A non-rotatable pin is arranged generally parallel to the first end of the flapper. A drag link is configured to pivot about the non-rotatable pin. The drag link includes a retaining feature and is substantially aligned with the protrusion on the flapper. When the flapper rotates to the second position, the retaining feature is configured to engage the protrusion to retain the flapper in the second position.
