Abstract: The invention is directed to a method for improving the fatigue behavior of the body (2) of a gas valve, the body comprising at least two bores (4, 10) and at least one bore intersection (20) defining an internal volume; wherein the method comprises the following step: subjecting the internal volume to an autofrettage by applying a pressure of comprised between 100 MPa and 500 MPa by means of a liquid. 10. The invention is also directed to a gas valve body (2) comprising at least two bores (4, 10) and at least one bore intersection (20) defining an internal volume with an internal wall; wherein the internal wall is treated by autofrettage resulting in compressive stresses at the intersection or at least one of the intersections.

Abstract: The invention is directed to a cover (4) for a tap of a gas cylinder (6), comprising a shell (7, 8) for housing the tap; and a hook (12) pivotally mounted on the shell (8), configured for securing the gas cylinder (6) to a horizontal bar (28). The shell (8) comprises reservations (30) on its external surface configured for receiving the hook (12) in a folded position so as to generally conform to said external surface. The invention is also directed to a gas storage assembly comprising a gas cylinder (6), a tap and a cover (4).

Abstract: The invention relates to a device for controlling the flow and/or pressure of a pressurized gas, and specifically to a tap for a pressurized-gas cylinder. The tap includes a body having a gas inlet, a gas outlet, and a passage connecting the inlet to the outlet. The tap also includes a valve for closing the passage, as well as a pressure indicator downstream from the closing valve. The pressure indicator is translatably operated and includes just two stable positions, i.e. one that corresponds to the presence of pressure, and the other to the absence of pressure.
