Abstract
An assembly for limiting excess flow includes a seat and a disc. The seat has an inner ring, an outer ring having a top surface tapering in a downstream direction from outer ring towards the inner ring, and a plurality of legs attaching the inner ring to the outer ring. The disc attaches to the inner ring and extends radially outwardly therefrom. The disk has an axially downstream surface that flexes into contact with the outer ring if the flow exceeds a limit around the disc, and a shoulder spacing the axially downstream surface from the inner ring to space the disc axially from the outer ring.
