Abstract
A conduit vent-and-valve combination especially adapted for tank ships employing gas-inerting of cargo tanks. It includes location of the vent and valve adjacent to one another in the conduit, and employs mechanical interlock between the valve hatch cover and an extension of the valve stem in order to prevent closing the hatch unless the valve is fully open.
