摘要： 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.

摘要： The control valve according to the present invention has a high durability, so that the valve is not easily damaged even in case that the valve is provided in a corrosion gas current path. The valve has a construction such that a diaphragm (4) is contained in the valve body (2), which has a valve chamber (23) between the gas current in path (25) and the gas current out path (26). The diaphragm 4 is urged against an opening (252) formed in the center of the valve seat 231 in the valve chamber (23) to open and close the opening. The valve has a valve control member (5), which has a clamping member (3) to clamp the diaphragm and is made to contact to the diaphragm from outside to open and close the opening. The diaphragm has an urging member (41) made of ceramic, which is fixed to the opening (252) side of the diaphragm so that the resistance to corrosion of the diaphragm is improved.
