Abstract
An assembly for limiting excess flow includes a housing having an internal bore defined by a first diameter, a seat held fixed within the internal bore, and a diaphragm defined by a second diameter that is less than the first diameter. The seat provides a sealing surface and the diaphragm is coupled to the seat by at least one leg. The diaphragm is spaced apart from the sealing surface during normal flow conditions and is in engagement with the sealing surface when a predetermined flow condition is exceeded.
