A CYLINDER VALVE FOR PRESSURIZED GAS CYLINDER AND A GAS CYLINDER COMPRISING SUCH A VALVE

摘要

A cylinder valve comprising a body (1) including a mounting end (3) for attachment in the opening of a pressurized fluid cylinder (2), a internal withdrawing circuit (4) comprising a first end (14) located at the mounting end (3) and a second end (24) located at an outlet port (5) located in the body (1), the withdrawing circuit (4) comprising, an isolation valve and a regulating device (7) for regulating selectively the flowrate and/or the pressure of the fluid flowing in the withdrawing circuit (4), the isolation valve and the regulating device (7) being controlled by manual actuating organ(s) (16, 17) located on the body (1), the actuating organ(s) (17) controlling the regulating device (7) 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, characterized in that the cylinder valve comprises a return organ (8) urging by default the actuating organ (17) controlling the regulating device (7) toward its first position
