Abstract
A container valve, attached to a gas container, wherein the container valve has a pressure reducing function, and is inside a valve block in the gas container. In the valve block, the container valve comprises a gas filling passage in which a filling valve is installed, a gas lead-out passage in which a lead-out valve is installed, and a pressure regulator arranged at an upstream side of the lead-out valve in the gas lead-out passage. The container valve can safely supply gas under a reduced pressure for use by opening the container valve of a container whose pressure is high and gas can be filled easily into the container. The container valve can be miniaturized and the purging operation for supplying high purity gas can be performed.
