摘要：
A valve assembly for a dispenser. The valve assembly includes a valve body (54) that extends about a longitudinal axis and defines an outer surface and an inner passageway. A valve stem (62) extends through the inner passageway and includes an outer stem surface, an inner stem surface opposite the outer stem surface, a fin (96) extending radially outward from the outer stem surface, and a first orifice extending from the outer stem surface to the inner stem surface. The fin operatively engages a portion of the inner passageway forming a first seal and providing controlled dispensing through the orifice (108). A valve seal may be joined to the valve steam (62). The vale seal may operatively engage a portion of the valve body forming a second seal.
