Abstract

The interior of the valve includes a conventional safety valve which operates in the event of an external pipe breakage consisting of a spring loaded valve disc on a hollow shaft screwed into the main valve piston the top end of the shaft leads to a channel with an enlarged nozzle directed against a blow off valve or a shut off valve for level indication in the top of the valve handle/knob. The lower endof the shaft may have a threaded sleeve coupling to a level gauge pipe passing into the cylinder. Valve gives increased safety when filling fixed or portable butane/propane cylinders.
