Patent abstract
A poppet valve assembly is sized and constructed for insertion into the lower portion of a flow control valve used within the opening of a cylinder for storing a compressed gas. When the flow control valve is removed, the normally open poppet valve assembly of the present invention is closed by escaping pressure of the compressed gas. The pressure of the compressed gas causes seals to be formed within the poppet valve assembly of the present invention between the exterior of a substantially hollow movable seat plug and the interior of a substantially tubular valve body.
