  • Excess flow valve with cage
    Patent number: 9383025
    Abstract: An assembly for limiting excess flow includes a housing having an internal bore that defines a seat. A cage is positioned within the internal bore and includes an upstream end and a sealing surface at a downstream end. A back plate with at least one magnet is seated within the internal bore upstream of the cage. The cage moves away from the back plate when a predetermined flow condition is exceeded such that the sealing surface engages the seat.
