Valve for pressurized or liquefied gas cylinder comprising a valve body (12) with a gas flow passage (16) running between an inlet opening (18) and an outlet opening (20); and a sealing seat (30) inside the passage (16) of the valve body with which a plugging member (34) is associated. A control head (14, 114) is mounted removably on the valve body (12) and includes an axial control rod (60, 118) cooperating with the plugging member (34) in order to move it between a closed position in which it rests on the sealing seat (30), in order to block the flow into the passage (16), and an open position in which the plugging member (34) is separated from the sealing seat (30), in order to enable the outflow. A locking means (82) is integrated with the valve body (12) and enables the plugging member (34) to be locked onto the sealing seat (30) when the control head (14, 114) is separated from the valve body (12).
