Abstract: An excess flow valve (EFV) is disclosed that has an efficient and durable construction. The EFV is efficient in terms of both size and cost. It is durable partly due to a design with few parts and also because of optional all metal construction. In some embodiments, an intumescent material is included that expands to close off the valve by pressing the valve plug into sealing engagement with the valve seat and permanently stopping the flow of gas when a pressure differential or flow velocity threshold is exceeded.
