Even if the pressure in the container is high, by opening the container valve, it is possible to safely supply the gas under reduced pressure at the consumption pressure, and also to easily fill the gas into the container and to miniaturize it. Provided is a container valve with a pressure reduction function capable of reliably also purging operation for gas supply.n n n Forming a gas filling passage 14 having a filling valve 13 and a gas extracting passage 16 having a discharge valve 15 in the valve block 12 mounted to the gas container 10; At the same time, a pressure reducing valve 17 is provided on the primary side of the discharge valve 15 in the gas discharge flow path 16. |
