  • INSERT CHECK VALVES AND METHODS
    Publication number: 20190383407
    Abstract: Inlet check valves and methods can include a seat body, a movable disc, a spring, and a disc retention cage. The disc retention cage captures the movable disc to the seat body through retention elements, which engage in a groove circumferentially disposed around a flange of the seat body. The movable disc has a stem on the outlet side, which guides the movement of the disc by engaging with a through-hole in the disc retention cage. A compression spring maintains the movable disc in a normally closed position against the seat body.
