A valve (20) has a valve housing (22) with a central passage (28) extending axially through the valve housing (22). Aperture (40) in the valve housing connect a second passage (38) to the central passage (28) to extend through the valve housing. A poppet valve member (24) is configured for sealing engagement of the central passage (28). The valve member (24) is urged into sealing engagement with the central passage (28) by internal pressure in a container (36) on which the valve (20) is provided. The valve member (24) and the valve housing (22) are configured so that the valve member (24) will drop away from sealing the central passage (28) when the pressure in the container (36) is insufficient to hold the valve member (24) in sealing position against the central passage (28) to leave the valve (20) in a permanently open state. An annular valve member (26) seals the second passage (38 ) in the same manner.
