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.

Abstract: A springless shear protection device for use with a valve, the device comprising a poppet, the poppet including a bore. The poppet including first and second openings at distal ends of the poppet. A seat plug is disposed in the poppet bore, the seat plug is moveable within the poppet bore. A shear tube with first and second ends extending through the first opening of the poppet, the first end abutting the seat plug through the first opening of the poppet and the shear tube displacing the seat plug from the top of the poppet bore. The poppet is attachable to the valve and when attached a compressed gas or liquid passes through the poppet into the valve. When the shear tube is removed, the seat plug forcibly engages the top of the poppet bore and the seat plug blocks the flow of the compressed gas or liquid.

Abstract: A relief device for a high-pressure gas container, comprising a main body having a generally uniform outer circumference and that defines a primary bore, the primary bore in fluid communication with an interior volume of the high-pressure gas container, the main body having a secondary bore, the secondary bore located within the outer circumference and in fluid communication with the primary bore, a spud assembly seated in the secondary bore, the spud assembly including a rupture disc that relieves to the atmosphere the contents of the container when the container reaches a certain pressure, the rupture disc located within the secondary bore and within the outer circumference, the spud assembly and rupture disc fixedly attached.
