Claim:
1. A fluid shutoff valve assembly for a fluid filling line, the valve assembly having a fluid flow path defining a direction of fluid flow, the assembly comprising: a fluid inlet orifice in fluid communication with a source of a fluid, the fluid inlet orifice allowing the fluid to flow in the direction of fluid flow from the source of the fluid into the fluid flow path of the valve assembly, wherein the fluid entering into the fluid inlet orifice is at a pressure greater than atmospheric pressure; a fluid outlet orifice in fluid communication with the fluid flow path of the valve assembly and through which the fluid may flow out of the valve assembly; a fluid shutoff valve in fluid communication with the fluid inlet orifice and the fluid outlet orifice, the fluid shutoff valve having a fluid blocking portion and a fluid flow-through portion, the fluid shutoff valve being moveable from a filling position wherein the fluid flow-through portion is aligned with the fluid flow path to a closed position wherein the fluid blocking portion is aligned with the fluid flow path, wherein the fluid shutoff valve is oriented such that the fluid shutoff valve moves in a direction that is generally perpendicular to the direction of fluid flow at a location where the fluid shutoff valve intercepts the fluid flow path; and a pressure isolation valve in addition to the fluid shutoff valve, the pressure isolation valve being located upstream of the fluid shutoff valve and configured to shut off the source of fluid from the fluid flow path while the fluid shutoff valve is in at least a partially open configuration, wherein the pressure isolation valve is configured to close before the fluid shutoff valve.
