A valve cage () for a control valve () incorporates a plurality of throttle channels () which extend from an inner contour of the valve cage () to its outer contour and penetrate the valve cage (), each throttle channel () having an inlet opening () on the inner contour side and an outlet opening () on the outer contour side when viewed in the flow direction (S). When viewed in the circumferential direction (u), the valve cage () has a plurality of arcuate outer contour portions () which are each separated from one another via a step () acting as a tear-off edge, and the throttle channels () are arranged so that they extend such that the outlet openings () of the throttle channels () on the outer contour side are arranged in the step () between two outer contour portions ().

Valve cage for a control valve

The invention relates to a valve seat and cage assembly () comprising a valve cage () and a valve seat (), the valve seat () being adapted to be screwed into the valve cage (), which valve cage (), in a connection portion () thereof, has a valve cage connection inner diameter (D) in which the connection portion () of a valve seat () engages with its valve seat connection outer diameter (D) and thus provides radial centering, a screw connection portion () and a shoulder (), with the shoulder () serving as an axial stop between the valve cage and the valve seat, and with the valve seat () and the valve cage () being pressed against one another with an axial contact pressure component. The invention is characterized in that the screw-connection portion is located between the connection portion () and a shoulder (), with the valve cage connection inner diameter (D) and the valve seat connection outer diameter (D) forming a fit with one another that will act to center the valve seat and the valve cage.

Valve seat and cage assembly

A valve component includes a valve housing having a passage extending along a longitudinal axis; a valve component mountable on the valve housing; a seal to circumferentially seal between the valve housing and the valve component; and a contact abutment to be disposed in the axial direction between the seal and valve housing, and which is configured to be movable in a pre-assembled state relative to the valve housing and the valve component. In an assembled state, the seal can be inserted into an annular-groove-shaped seal receptacle limited by the valve component, valve housing, and contact abutment. The valve housing, valve component, and contact abutment can be matched to each other such that the seal receptacle is reduced when the valve component is mounted on the valve housing, the contact abutment being supported on the valve housing. The contact abutment can undergo a relative movement relative to the valve component.

Valve component arrangement and a control valve with a valve component arrangement

In a throttle body for reducing the fluid pressure, particularly at a control valve, preferably for arranging in a process fluid line, of a process plant, such as a chemical plant, particularly a petrochemical plant, a power plant, a brewery or the like, with a plurality of channels extending from an upstream channel inlet to a downstream channel outlet, it is foreseen that an at least section-wise curved course of at least one of the plurality of channels between the channel inlet and the channel outlet deviates from a two-dimensional extension.

Throttle body with a plurality of channels extending three-dimensional spiral-shaped

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.

Globe valve and arrangement for a globe valve

Sealing arrangement of a fluid system for use with cryogenic media, said arrangement comprising a sealing ring in which a first system component is connected to a second system component by means of the sealing ring which sealing ring further has a first sealing surface which sealingly engages the first system component and the sealing ring has a second sealing surface which sealingly engages the second system component which first sealing surface and second sealing surface of the sealing ring are designed such that the first and second system components in the area of the sealing surfaces extend radially within the sealing ring in a section plane which extends parallel to the direction of contraction, and the sealing ring when exposed to cold, contracts thermally to a greater extent than the first system component and the second system component.

Sealing arrangement

The invention refers to a cage valve comprising a valve cover () and a valve cage, which latter comprises a retaining element () and a plurality of throttle elements () which are designed in the form of a hollow section. The invention is characterized in that the valve cage is connected to the valve cover ().
