Zusammenfassung:	A valve (20) and flow control element (22) are provided for use with a dunnage bag (24). The valve (20) includes a valve housing (40) that carries an actuator (36) and the flow control element (22). The housing (40) defines a flow passage (44), and a seal surface (48) around the flow passage. The flow control element (22) includes a peripheral attachment portion (60), a resilient, intermediate portion (62) extending generally laterally inwardly from the peripheral attachment portion and defining at least one flow aperture (64); and an imperforate central portion (68) extending generally laterally inwardly from the intermediate portion and including a seal (70) for sealing against the housing seal surface with the flow control element in a normally closed position. The intermediate portion of the flow control element accommodates movement of the seal between the normally closed position and an open position away from the seal surface in response to the central portion being subjected to an opening force, thereby permitting flow of a fluent substance through the flow passage and the at least one flow aperture.
