  • Valve removal tool, gas cylinder recycle kit, and process for removing valves from gas cylinders
    Patent number: 5842260
    Abstract: Compressed gas cylinder valve removal tools and a kit are disclosed. A body portion of the tools mate with a corresponding portion on a compressed gas cylinder valve assembly. A stem portion of the tools is advanced through the body portion and into the valve assembly of the compressed gas cylinder. A punch portion of the stem impinges against the valve of the valve assembly and punches out the valve into the compressed gas cylinder. A gas vent path is provided through the valve removal tool to allow residual gas within the compressed gas cylinder to escape through the tool to atmosphere while the valve is being punched out. In an alternative embodiment, the valve removal tool includes portions which mate with corresponding portions on a compressed gas cylinder valve, to unscrew the valve from the valve assembly.
