An embodiment of the present invention relates to a valve apparatus that is designed to help protect users of liquefied propane gas ("LPG") powered equipment from being injured while using, connecting, or disconnecting a coupler that connects an LPG supply line to an LPG container. The valve apparatus may, for example, prevent LPG from escaping into the environment while the supply line is being, or after it has been, disconnected. |
