Abstract: 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.

Abstract: A shut-off device for a fluid includes a housing conducting the fluid, an inflow opening provided in the housing, an outflow opening provided in the housing, a flow channel formed in the housing between the inflow opening and the outflow opening, and a blocking device arranged in the flow channel. The blocking device has a blocking body receptacle and a blocking body movable in the blocking body receptacle. The flow cross-section for the fluid in the blocking device, and thus in the flow channel, can be changed by moving the blocking body in the blocking body receptacle. A reliable detection of the position of the blocking body is ensured in that an ultrasonic measuring device is arranged in or aligned on the housing such that the position of the blocking body can be determined by means of the ultrasonic measuring device.
