1. A vent limiting device, comprising:
a housing having an interior surface, a fluid inlet, a fluid outlet, and a first fluid passageway in fluid communication with and located between the fluid inlet and the fluid outlet, the interior surface including a first sealing surface that defines a portion of the first fluid passageway;
a stem having a first end, a second end located opposite the first end, and an axial portion located between the first end and the second end; and
a poppet having a first end, a second end located opposite the first end, a second sealing surface that defines a portion of the first fluid passageway, and a bore that defines a second fluid passageway in fluid communication with and located between the fluid inlet and the fluid outlet, the first end of the stem being rigidly coupled to the poppet, the poppet being slidable in an axial direction within the housing between an open position and a closed position, the second sealing surface contacting the first sealing surface when the poppet is in the closed position to close off the first fluid passageway;
wherein the second end of the stem includes a retaining flange visible from outside of the housing, the retaining flange contacting a retaining flange seat of the housing when the poppet is in the open position, the retaining flange spaced apart from the retaining flange seat when the poppet is in the closed position, the retaining flange providing a visual indication of the poppet being in the closed position.
