Beschreibung
Zusammenfassung:	A valve includes a fluid inlet passage having a fluid inlet, a fluid outlet passage, an orifice between the fluid inlet passage and the fluid outlet, and a moveable valve plug adapted to move with respect to the orifice to vary the flow of fluid between the fluid inlet passage and the fluid outlet passage. A movable valve stem is attached to the valve plug and a travel limiting device is attached to the valve stem. The travel limiting device permits the valve to be placed in one of a plurality of desired flow configurations.
