Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fluid flow control device.SOLUTION: The fluid flow control device includes: a body 16 defining an inlet 18, an outlet 20, and a fluid flow path 22 extending from the inlet to the outlet; a valve seat ring 24 coupled to the body and defining an orifice through which the fluid flow path passes; a cage 30 coupled to the body and defining an interior bore, wherein the cage includes at least one passage through which the fluid flow path passes; a throttling element 14 sized for insertion into the cage interior bore and movable along an axis between open and closed positions, where the throttling element defines a sealing surface 52 oriented substantially parallel to the axis; a seal 12 positioned to engage the sealing surface when the throttling element is substantially in the closed position, thereby to restrict fluid flow through the valve seat ring orifice.
