A valve for pressurized fluid having a body housing a fluid circuit having an upstream end configured to be placed in communication with a reserve of pressurized fluid and a downstream end configured to be placed in communication with a user of fluid, the circuit having a collection of valve shutter(s) having at least one shutoff valve shutter allowing the circuit to be closed or opened, the valve having a member for manually controlling the collection of valve shutter(s), the control member being mounted with the ability to move on the body between a rest position in which the collection of valve shutter(s) is in a position in which the circuit is closed and an active position in which the control member actuates the collection of valve shutter(s) into a position in which the circuit is open with a first bore section.

Embodiments of a propane tank valve are provided. In one embodiment, the propane tank valve includes a plug with a tapered portion, the plug moveable between closed and open positions relative to a valve passageway. Upon the plug being in the closed position, the tapered portion of the plug is positioned within the valve passageway. Upon the plug being initially moved from the closed position to the open position, the tapered portion of the plug is sized and configured to initially minimize the gas flow from the valve passageway and through a flow limiting device configured to be coupled to the propane tank valve such that movement of the tapered portion from the closed plug position initially forms a gap between a tapered surface of the tapered portion and an internal surface of the valve passageway.

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 pneumatically operated gas valve mounted on a vessel containing pressurized gas. The gas valve includes a piston positioned in a cylinder with one closed end so that the piston seats against a gas outlet to close the gas valve. A control reservoir is formed in the cylinder between the piston and the closed end of the cylinder. Upon filling vessel, some of the pressurized gas enters the control reservoir to provide a control pressure behind the piston. Actuating the control mechanism vents the control reservoir, resulting in the gas valve opening rapidly to release the pressurized gas in the vessel through an exhaust port of the gas valve.

There is provided an apparatus comprising a torque motor comprising a spring, armature, flapper assembly (“SAFA”), a body, wherein the spring, armature, flapper assembly is mounted onto the body, and a cap enclosing the spring, armature, flapper assembly. One or more cooling passages are provided within the body and are configured to receive cooling air and direct the cooling air onto the spring, armature, flapper assembly of the torque motor.

A dispenser includes a housing, an inverted container disposed in the housing, a outlet nozzle, a pump, a first check valve, and a second check valve. The container holds a fluid. The pump is disposed between the container and the outlet nozzle. The pump includes a pump inlet in fluid communication with the container, a pump outlet in fluid communication with the outlet nozzle, and a pump chamber in fluid communication with the pump inlet and the pump outlet. The pump chamber is movable between an expanded position and a compressed position. The first check valve is disposed between the pump and the outlet nozzle, and the first check valve has a first cracking pressure. The second check valve is disposed between the first check valve and the outlet nozzle, and the second check valve has a second cracking pressure. The second cracking pressure of the second check valve is greater than the first cracking pressure of the first check valve.

A safety release bleeder valve serving as a plug includes a barrel having an exterior surface and an interior throughbore surface for matingly receiving a plug having a top end with exterior threads and an interior socket for receiving a driver tool for moving the plug between an open venting state and a closed non-venting state.

An electromagnetically actuated piston slide valve and an assembly set for such a valve with which an NC valve and an NO valve can be fabricated. Such a valve of the NC construction type comprises a valve housing with corresponding connectors and a fluid passage. A slide coupled with a magnetic armature is provided for regulating a free cross-sectional area of the fluid passage. A first spring urges the slide in an opening direction and a second spring urges the slide in an opposite closing direction, wherein the first and the second spring are adapted such that, in the electrically unenergized state of the coil, the slide adopts a position in which the fluid passage is closed.

The switch valve for high-pressure gas includes: the flow path through the lower side; the valve body that divaricates and extends towards the upper side of the flow path, and forms a switch with an opening in the upper side; a valve with a long vertical rod shape, the lower side inserted inside the switch, and with a first thread formed on the upper outer side; a handle having the hollow inside and the closed cylindrical upper side, and placed on the upper side of the valve body accommodating the upper side of the valve inside; a second thread corresponding to the first thread and formed on the inner surface of the handle; a valve cover; a pressure scatter hole that through the inside center axis of the handle to connect with the flow path. The gas pressure inside the handle and the flow path is kept in equilibrium.
