Abstract: A control valve incorporates a valve housing with a main body having a valve inlet and valve outlet, a valve seat in the flow duct between the valve inlet and valve outlet, a valve cage in the flow duct between the valve inlet and valve outlet, and a valve member which is movable in the axial direction (a) relative to the valve seat and valve cage and connectable to an actuator rod of a drive via a drive rod. The valve housing has an extension body extending the main body in the axial direction (a) and a valve cover which closes the extension body and through which the actuator rod can sealably pass. The control valve further includes a circulation barrier in the valve housing which prevents circulation of a process medium in the extension body. The circulation barrier and the valve cage are in contact with each other via contact pressure surfaces opposite one another in the axial direction (a). The circulation barrier and valve cage components are jointly fixed in the valve housing via a fastening means.

Abstract: A valve cage (100) for a control valve (10) incorporates a plurality of throttle channels (104) which extend from an inner contour of the valve cage (100) to its outer contour and penetrate the valve cage (100), each throttle channel (104) having an inlet opening (106) on the inner contour side and an outlet opening (110) on the outer contour side when viewed in the flow direction (S). When viewed in the circumferential direction (u), the valve cage (100) has a plurality of arcuate outer contour portions (112) which are each separated from one another via a step (114) acting as a tear-off edge, and the throttle channels (104) are arranged so that they extend such that the outlet openings (110) of the throttle channels (104) on the outer contour side are arranged in the step (114) between two outer contour portions (112).

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A process for enriching and separating polyunsaturated fatty acid (PUFA) acyl groups in a fatty acid mixture, which mixture contains other non-PUFA fatty acid acyl groups, is disclosed.

Abstract: A mixture containing fatty acid glycerides which has a high percentage content of PUFA acyl groups and a low percentage content of saturated fatty acid acyl groups is described. A process which enables the PUFA acyl groups in a mixture containing fatty acid glycerides (for example a fish oil) to be enriched and, at the same time, the content of saturated fatty acid acyl groups to be maintained at a low content is described. The process is a hydrolytic process or an alcoholysis in which the fatty acid acyl groups to be enriched are hydrolytically or alcoholytically released from the fatty acid glycerides slowly, if at all, the process being carried out in the presence of a lipase.
