Valve for pressurized fluid and a container or a set of containers for pressurized fluid

A valve for a pressurized fluid, comprising a body incorporating a fluid circuit having an upstream end configured to be placed in communication with at least one tank of pressurized fluid and a downstream end configured to be placed in communication with a user of fluid, the circuit comprising a shut-off member mounted with the ability to slide in the body, the shut-off member allowing the closing or opening of the circuit,

• the valve comprising a shut-off member control member controlling the valve shut-off member, the shut-off member being mounted with the ability to slide in the body between a position for closing the circuit when the control member is in a position of rest, and a position for opening the circuit when the control member is in an active position,
• the valve comprising a deformable member interposed between the shut-off member and the control member, the deformable member being configured, when the control member is moved from the position of rest to the active position,
• to press against the shut-off member and cause it to slide into the position for opening the circuit, and
• to deform irreversibly under the action of the shut-off member when a force applied by the pressurized fluid to the shut-off member exceeds a predetermined threshold, and thus allow the shut-off member to slide into the position for closing the circuit.
