Abstract: A cryogenic valve comprises a valve body, a plug, an actuator, a kinematic chain comprising a driving member displaced by the actuator, and a transmission structure transmitting the movement of the driving member to the plug. A tubular bellows is arranged around the transmission structure and has internal corrugations protruding toward an interior of the tubular bellows Protections made of a material with a low coefficient of friction, are placed inside the tubular bellows on the internal corrugations. The protections are displaced with the internal corrugations along an axis of displacement when the driving member is displaced along the axis of displacement.

Abstract: A valve for flowable media having a valve housing and an elongate closure member arranged therein and which can be axially moved in a medium channel of the valve by a controllable actuator and which in a closed position abuts a valve seat and closes a discharge opening connected to the medium channel, and which is connected to a sealing element to seal the medium channel, namely, a part-piece of an elongate bellows, which moves in an axial direction during movements of the closure member and which is a hollow member made of metal, wherein another part-piece of the bellows is fixedly supported in the valve. The relative axial position between the bellows and the valve seat is adapted to a production-related deviation of the longitudinal dimension of the bellows used from a desired longitudinal dimension so that this deviation is compensated for.

Abstract: A cooled isolation valve includes a valve body, a stationary element coupled to the valve body, and a movable closure element movable with respect to the stationary element between a closed position in which the movable closure element and the stationary element are brought together and an open position. One of the movable closure element and the stationary element includes a sealing element. In the closed position of the movable closure element, the sealing element provides a seal between the movable closure element and the stationary element. A fluid channel is formed in contact with the movable closure element and movable with the movable closure element with respect to the stationary element, such that a fluid in the fluid channel effects heat transfer in the movable closure element. A bellows of the isolation valve can include a metallic substrate with a ceramic coating.

Abstract: A gas inlet valve with incompatible materials isolation is provided. The valve may include a piston that seals against a surface when in a closed position and that permits gas to flow through the valve and out the outlet port when in an open position. A bellows may protect the actuation mechanism of the piston from gas that may be present in the valve when the valve is in the open or closed position, and the piston may include a second seal interface that seals the bellows off from the gas flow area when the valve is in the open or closed position.

Abstract: A valve for controlling fluid flow from an inlet of a pipe fitting to at least one outlet of the pipe fitting at an angle to the inlet. The pipe fitting includes an inner collapsible bellows fixed at a position opposite the inlet. The bellows has a support annulus at the other end adjacent the inlet, whereby, in a closed position, the bellows prevents fluid flow from the inlet to the at least one outlet as the fluid is trapped within the bellows. In an open position, the fluid can flow from the inlet to the at least one outlet when the bellows is collapsed.
