Abstract: A protection device for a container for pressurized gas comprises a main body which is configured so as to at least partially close a valve body of the container and a coupling element being rotatably connected to the main body. The main body comprises an abutment element which extends in the direction away from the main body, the abutment element being configured in such a manner that, when the coupling element is in an open configuration, a receiving cavity is defined between the abutment element and the arms and is configured to receive a bar-shaped element.

Abstract: A valve assembly for pressurized containers includes a main structure, a rotary control element rotatably connected to the main structure and configured so as to allow a gas flow through the valve assembly in accordance with an angular position thereof about a main rotation axis, a detection device which includes an angular position sensor and a movable member. The angular position sensor is configured to detect the angular position of the movable member about an auxiliary rotation axis. The movable member is rotatably supported on the main structure and the angular position sensor is fixed to the main structure. The valve assembly further includes a movement conversion mechanism configured so as to convert the movement of the rotary control element about the main axis into a corresponding rotational movement of the movable member about the auxiliary axis which is different with respect to the main rotation axis.

Abstract: A valve comprising a valve body having an outflow pipe and comprising a valve seat which defines a first zone of the outflow pipe upstream of the valve seat and a second zone downstream of the valve seat, and a cam follower which is capable of moving with respect to the valve seat along an axis X between an open position, at least one partially open position and a closed position, and comprising a valve head which is capable of moving into abutment in a fluid-tight manner against an abutment surface of the valve seat, a rod which is fixedly joined to the valve head, in such a manner that there is defined a through-opening between a lateral surface of the rod and a corresponding internal surface of the valve seat which faces the lateral surface of the rod, characterized in that the through-opening is equal to a first value A when the cam follower is in the at least one partially open position and is equal to a second value B when the cam follower is in an open position, with B>A.

Abstract: A valve integrated pressure regulator (VIPR) device is provided that includes a gas flow valve arrangement, a shroud and digital gauge display that can be attached or coupled to a gas cylinder, and which can monitor the amount or pressure of the gas in the gas cylinder. Features of the disclosed valve integrated pressure regulator device include an electronic control, electronic alarm and the electronic display that are powered by a battery that may be disposed within the shroud. The battery and/or electronic control are accessible via a removable access panel disposed on the front surface of the shroud.
