CYLINDER VALVE FOR PRESSURIZED GAS CYLINDER AND GAS CYLINDER WITH SUCH CYLINDER VALVE

PROBLEM TO BE SOLVED: To provide a valve assembly in which a valve can be operated with an appropriate procedure in a high pressure gas discharging circuit.SOLUTION: A cylinder valve is provided which includes: a body 1 including a mounting end part 14 for attachment in the opening of a pressurized fluid cylinder 2; an internal withdrawing circuit 4 including a first end part 14 located at the mounting end part and a second end part 24 located at an outlet port 5 located in the body 1, the withdrawing circuit 4 including an isolation valve 6 and a regulating device 7 for regulating selectively the flow rate and/or the pressure of the fluid flowing in the withdrawing circuit 4, the isolation valve 6 and the regulating device 7 being controlled by manual actuating organs 16, 17 located on the body 1, the actuating organ 17 being mobile relative to the body 1 between a first position setting a flow rate or a regulated pressure to defined minimum value and at least a second position setting a flow rate or a regulated pressure to a defined maximum value, the cylinder valve further includes a return organ 8 urged by default of the actuating organ 17 controlling the regulating device 7 toward its first position.
