Definitions

  • the invention relates to a gas distribution valve block, with or without an integrated expansion system, for equipping a gas container or the like, and making it possible to reduce the risk of a pressure reading error, in particular by virtue of flexibility increased positioning of the elements subjected to high pressure, and a gas distribution assembly comprising a gas cylinder, in particular medical gas, and such a valve block fixed to the gas cylinder, and preferably with a rollover of protection arranged around the valve block to protect it from shocks and dirt.
