A process including: an assembly step of assembling a sealed case onto an existing pipe; a cutting step of forming a first opening of a groove shape elongated in a pipe axis direction of the existing pipe; a second boring step of forming a circular second opening at a position of the existing pipe that opposes the first opening; and an insertion step of inserting, in a valve-open state, a butterfly-shaped valve element that is integral with a valve rod, which runs through the first and second openings, into the existing pipe 1 through the first opening until a tip portion of the valve rod protrudes from the second opening.

A valve flap assembly for an exhaust-gas valve has a first valve flap provided for closing a first flow cross-section and a second valve flap provided for closing a second flow cross-section. The second valve flap is mounted for swiveling movement relative to the first valve flap. In addition, a valve arrangement for an exhaust system is presented which comprises such a valve flap assembly. Furthermore, an exhaust system for an internal combustion engine of a vehicle is presented, which comprises such a valve flap assembly and/or a valve arrangement. A vehicle having such an exhaust system is also disclosed.

According to various aspects of the disclosure, a valve assembly for a vacuum chamber housing may have: a valve housing, which has a substrate transfer gap; a valve flap, which is mounted so as to be rotatable about an axis of rotation, thus enabling said flap to be rotated into a first position and into a second position, wherein the axis of rotation is arranged in the substrate transfer gap, and wherein the substrate transfer gap is extended longitudinally along the axis of rotation; wherein the valve flap closes the substrate transfer gap in the first position and is arranged adjacent to the substrate transfer gap in the second position.

An arrangement for a globe valve for adjusting a process fluid can include a valve housing having an inlet and an outlet connected by a passage, a valve cage to linearly guide a valve member of the globe valve in an axial direction, and a position lock (securing device). The valve cage can include a passage channel(s) extending transversely in the axial direction. The valve cage can be arranged in the valve housing where: the valve cage circumferentially surrounds the passage opening with respect to the axial direction, and a radial outer side of the valve cage with respect to the axial direction is in contact with a radial inner side of the valve housing with respect to the axial direction. The position lock fixes a relative position of the valve cage relative to the valve housing and arranged on the radial outer side and/or on the radial inner side.

An example wire ring is configured as a partial polygon. The partial polygon has a plurality of curved sections interposed between a plurality of straight sections. The wire ring is configured to contact a base of an annular groove of an external component of a valve at multiple contact points. The wire ring is also configured to contact a respective base of a respective annular groove of an internal component of the valve disposed, at least partially, within the external component at multiple respective contact points.

A valve for controlling a fluid flow includes a valve body, a shutter component configured to be able to transition from an open position allowing the circulation of fluid, to a closed position preventing the circulation of fluid. The component is characterized in that it includes a fixed conical support integral with the valve body, a conjugate conical flap rotationally movable relative to the fixed support, and fluid passage apertures respectively arranged in the conical flap and in the fixed support, and an actuator of the shutter component adapted to be able to control the position of the shutter component.
