Beschreibung
Zusammenfassung:	Embodiments of a valve device that reduces noise and vibration that may occur during low flow conditions in fluid couplings (e.g., valves and flow regulators). These embodiments utilize a plug (108) and seat (106) arrangement with geometry to prevent pressure differentials that cause the plug element to open and close in a cyclic pattern. In one embodiment, the valve device includes a seat element with an aperture (118) and a plug element with a boss (122) that extends into the aperture when the plug element contacts the seat element. The boss has an outer surface that forms a gap (128), which defines an annular area proximate the point of contact between the seat element and the plug element that is sized to reduce Venturi flow effects that cause the cyclic pattern to occur.
