Abstract

A valve for pressurized fluid having a body housing a fluid circuit having an upstream end configured to be placed in communication with a reserve of pressurized fluid and a downstream end configured to be placed in communication with a user of fluid, the circuit having a collection of valve shutter(s) having at least one shutoff valve shutter allowing the circuit to be closed or opened, the valve having a member for manually controlling the collection of valve shutter(s), the control member being mounted to allow the body to move between a rest position in which the collection of valve shutter(s) is in a position in which the circuit is closed and an active position in which the control member actuates the collection of valve shutter(s) into a position in which the circuit is open with a first bore section
