The invention relates to a cage valve () comprising a valve housing () with a valve inlet () and a valve outlet (), a valve cage () which is arranged between the valve inlet and valve outlet () in the flow channel, and a valve element () which is movably supported in the valve housing () in the axial direction (a) with respect to the valve cage (), wherein the valve cage () has a guide region, which guides the valve element () in the axial direction (a), and a throttle region, which has multiple throttle channels () that are mutually spaced in the axial direction and are arranged in a distributed manner when viewed in the circumferential direction (u), so that different throttle rates can be set on the basis of the axial position of the valve element () relative to the valve cage ().

Cage valve

In a valve housing for a globe valve for controlling a process fluid flow of a process plant (e.g. a chemical plant, petrochemical plant, a power plant, or a food processing plant), a passage opening is provided that can be closed by a valve member movable translationally in a vertical direction. The valve housing may define, in the vertical direction above the passage opening, a working space for accommodating the valve member. The valve housing may define a kettle space in the vertical direction below the passage opening. The valve housing may include at least one guide blade projecting radially into the kettle space for disturbing a process fluid vortex with vertical vortex axis of rotation filling the kettle space.

A globe valve (e.g. Flow-To-Open valve) can include an inlet opening with a circular shaped opening cross section defining a valve axis, a globe valve member movable in a vertical direction transversely to the valve axis and connectable, via a valve rod, to an actuator for actuating the globe valve member, and a passage opening with a circular-shaped passage opening cross section. The globe valve member closes the passage opening at a lowest actuating position, in the vertical direction, and a flow channel extending from the inlet opening to the passage opening defines a flow cross section. The surface size of the flow cross section decreases in a first section from the inlet opening, in a flow direction, to a transition point. The flow cross section, in the first section, is continuously oval shaped and the first section of the flow channel is continuously inclined downwards in the vertical direction.
