A valve assembly operable to fill a container with pressurized gas from a source thereof and to vent the cylinder and associated passage means in the valve assembly to atmosphere, the cylinder having a valve with a valve member spring biased to a closed position. The valve assembly has a valve housing within a main chamber, a supply port connectable to a source of pressurized gas, a fill port connectable to a cylinder to be filled, and a vent port communicating with the atmosphere, the supply port, fill port and vent port communicating with the main chamber. A valve body is mounted in the main chamber for movement therein and having a first passage operable in a first position of the valve body to connect the fill port to the vent port, a second passage operable in a second position of the valve body to connect the supply port to the fill port, and a third passage operable in a third position of the valve body to connect the fill port to the vent port. A valve opening member is movably mounted in the valve housing and actuated by the valve body when the body is moved to the second and third positions to engage and move the valve member of a cylinder secured to the fill port to an open position.
