Abstract: A valve assembly for pressurized containers comprises a main structure, a rotary control element which is rotatably connected to the main structure and which is configured so as to allow a gas flow through the valve assembly in accordance with an angular position thereof about a main rotation axis, a detection device which includes an angular position sensor and a movable member. The angular position sensor is configured to detect the angular position of the movable member about an auxiliary rotation axis. The movable member is rotatably supported on the main structure and the angular position sensor is fixed to the main structure. The valve assembly further comprises a movement conversion mechanism which is configured so as to convert the movement of the rotary control element about the main axis into a corresponding rotational movement of the movable member about the auxiliary axis which is different with respect to the main rotation axis.
