Tap for compressed or liquefied gas

摘要

The tap is designed for fitting onto a gas bottle and to allow both the drawing-off of gas and the filling of the bottle. To this end, the tap includes a filling circuit communicating with the inside of the bottle via a level valve which automatically closes at a specific level and a drawing-off circuit comprising at least one retention valve (22, 32) preventing filling of the bottle via the drawing-off circuit.
