ABSTRACT:
The present invention pertains to a valve for pressurized cylinders for liquified gases, such as butane, propane, and similar gases. This valve is characterized by the combination of: a first safety device which prevents any overfilling of the cylinder with gas in a liquid phase; a mechanism for releasing gas in a gaseous phase which is intended for normal consumption; a flow shut-off device which closes when the flow of gas in a gaseous phase exceeds a predetermined level; and a safety mechanism situated ahead of the shut-off device, according to the direction for releasing gas, the mechanism opening whenever the pressure of gas stored inside the cylinder exceeds the operating pressure.
