An apparatus for servicing a tank and/or a plug includes a valve having a first port sealingly couplable onto a tank port surrounding the plug, a second port, and a valve member operable between an open position providing a pathway between the first and second ports, and a closed position providing a sealed barrier between the first and second ports. The apparatus further includes an adapter sealingly couplable to the second port, and a plug displacement tool couplable to the adapter for displacing the plug relative to the tank when the first port is coupled to the tank port, the adapter is coupled to the second port, and the valve member is in the open position.

The invention relates to a gas supply device including a supporting frame (2) housing a plurality of cylinders (3) connected such as to form a circuit (4, 5) including a first coupling end (6) connected to the cylinders (3) via a first isolation valve (7) and a second separate coupling end (8) that is connected to the cylinders (3) via a second isolation valve (9) and a pressure release valve (10), the supporting frame (2) including an interface panel (20) comprising at least one opening enabling a user to access the circuit (4, 5), characterized in that the device comprises a member (16) for manually controlling the second isolation valve (9) including a pivoting lever, and in that the interface panel (20) includes a slot (21) for accessing the lever (16), said lever (16) being movable between a first position in which the lever (16) is in the plane of the interface panel (20) or set back from the latter within the volume of the frame (2) and a second position in which at least one portion of the lever (16) projects relative to the interface panel (20) through the slot (21).

A device for regulating the pressure of a compressed gas, comprising a body with a gas inlet, a gas outlet and a gas passage fluidly interconnecting the inlet and outlet; a mobile element carrying a shutter cooperating with a seat in the gas passage, the shutter and the seat forming a regulating valve; a hand-wheel operatively linked to a spindle rotatably mounted on the body; wherein the spindle is hollow and houses a spigot with a cam, the spigot being linked in rotation with the spindle and cooperating with a counter-cam spigot movable in translation but not in rotation relative to the body, and acting on the mobile element or on a shut-off valve for selectively shutting-off and opening the gas passage.

A valve for compressed gas, comprising a body extending longitudinally, with a gas inlet at a lower end of the body, a gas outlet and a gas passage fluidly interconnecting the gas inlet and the gas outlet; a shut-off device housed in the body and configured for selectively shutting-off and opening the gas passage; a lever pivotally mounted on the body, at an upper end of the body, and configured for actuating the shut-off device; a hook pivotally mounted on the lever for engaging with a counter-shape on the body and thereby holding the lever in a folded position along the body; wherein the upper end of the body comprises a cylindrical wall delimiting an upper bore, the counter-shape being an upper edge of the cylindrical wall.

A regulating valve device for a fluid cylinder includes a shut off valve having a ball tappet that actuates the shut off valve. A lever has a cam surface that interacts with the ball tappet as the lever is rotated to translate the ball tappet linearly and actuate the shut off valve. The lever is rotatable from a first valve closed position through a valve open position to a second valve closed position such that the valve open position is intermediate of the first and second valve closed positions. A pressure or flow regulating valve is downstream of the shut off valve. A handwheel is operatively connected to the pressure or flow regulating valve to adjust an outlet pressure of the pressure or flow regulating valve. The handwheel has an axis of operation that is offset from a longitudinal axis of the fluid cylinder by an acute angle.

A one-way valve device or a non-return valve mechanism in the valve device provides a higher retaining residual pressure without upsizing. A non-return valve cassette in a consumption valve device regulates gas flow. The cassette includes a check valve movable forward and backward between a valve-closed position and a valve-open position in an outlet secondary flow channel and movable backward to the valve-open position under pressure of the gas flowing upstream, and a first coil spring with a spring force biasing the check valve upstream. The first coil spring permits the check valve to move downstream against the upstream biasing when an upstream pressure is a predetermined pressure or greater. The check valve includes a downstream end smaller than an upstream end in an area communicating with an upstream space at the valve-closed position.

A device for regulating the pressure of a compressed gas, comprising a body with a gas inlet, a gas outlet and a gas passage; a mobile element biased by a main spring and carrying a shutter cooperating with a seat in the gas passage, the shutter and the seat forming a regulating valve, a shut-off valve with a shutter and a seat in the gas passage upstream of the regulating valve; an actuation assembly of the shut-off valve; wherein the shutter of the shut-off valve comprises a stem extending through the mobile element and the shutter of the element, for cooperating with the actuation assembly located in front of the element.

A valve comprising a body with an inlet, an outlet and a passage fluidly interconnecting the inlet and outlet; a shut-off device of the passage, with an actuating member movable along a longitudinal axis; a hand operating device of the actuating member, for selectively opening or closing the passage, and comprising a support element and a rotating element with at least one contact surface configured for sliding along at least one ramped surface on the support element, or vice versa, so as to convert rotation of the rotating element into a translation of the actuating member; wherein the body comprises two arms extending longitudinally and diametrically opposed relative to the longitudinal axis, with distal ends holding the support element.

A valve for a fluid, comprising: a body with an inlet, an outlet and a passage fluidly interconnecting the inlet and outlet; a shut-off device housed in the body and configured for selectively opening and closing the passage, the shut-off device comprising a main seat, a main closing element forming a channel extending there through and a pilot seat, a pilot closing element housed in the main closing element, a first compression spring, and a second compression spring; an actuating device of the shut-off device. The second compression spring is operatively mounted between the main closing element and the body and the first compression spring is stronger than the second compression spring.
