According to some embodiments, a pressure relief valve system comprises a valve body coupled to a pressure chamber. The valve body defines a vapor flow path between the pressure chamber and the atmosphere. A valve orifice in the valve body is configured to allow vapor to flow between the pressure chamber and the valve body. A vapor conduit comprises a vapor conduit first end coupled to the valve orifice and a second end opening into the pressure chamber. The vapor conduit forms a passageway between the vapor conduit first and second end. The vapor conduit also comprises a vapor conduit orifice near its first end. The vapor conduit orifice is configured to allow the vapor to flow from the pressure chamber into the vapor conduit. A gravity-operated valve positioned near the vapor conduit first end is configured to control the flow of vapor through the vapor conduit orifice.
