ABSTRACT:
A valve which intended to control the flow of a fluid, for example a gas, comprises a valve body (50), an internal member for opening and shutting-off the passage of the gases, an operating handwheel (56) connected to the opening and shut-off member, and means limiting movement of the operating handwheel (56) 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 (60) and of a mating stop (62), with frontal contact, arranged respectively on a rotary element and on the body of the valve (50) or vice versa. To ensure optimum contact between the stop (60) and the mating stop (62), the latter forms part of an element the angular position of which can be adjusted.
