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.
