Abstract: A valve apparatus especially well-suited for use in gaseous oxygen delivery systems. A valve apparatus is provided that substantially reduces the risk of fire in high-pressure oxygen systems. The apparatus is particularly well-suited for use as a plug valve on ordinary cylinder containers, but may be beneficially used in any pressurized gas system, particularly oxygen systems such as those encountered in many industrial facilities.
