A valve which intended to control the flow of a fluid, for example a gas, comprises a valve body (), an internal member for opening and shutting-off the passage of the gases, an operating handwheel () connected to the opening and shut-off member, and means limiting movement of the operating handwheel () and of the opening and shut-off member in the direction of opening of the valve. To avoid the valve jamming in the open position, said means limiting the movement of the operating member includes a stop () and of a mating stop (), with frontal contact, arranged respectively on a rotary element and on the body of the valve () or vice versa. To ensure optimum contact between the stop () and the mating stop (), the latter forms part of an element the angular position of which can be adjusted.

Valve

The valve (31) comprises at least two lateral openings (34, 36) which can be shut off by a plug (40) provided with an axial orifice (48) for the passage of gas and sliding axially in the casing (32) between a position in which the openings, (34, 36) are shut off under the influence of a spring (44) and an open position counter to the action of the spring (44) under the influence of the pressure of the filling gas, and a level valve (52) activated by a float (62) at the bottom of the casing (32). The plug (40) comprises an inner cavity (70), the bottom of which has a cross-section in the shape of an open 'V'. In this cavity (70) is a ball (72) which prevents the cylinder from being filled when the latter is inclined sufficiently for the ball not to be situated at the bottom of the cavity (70).
