ABSTRACT:
A top-entry check valve having a seat, cage, disc and removable bonnet utilizes pin fasteners to prevent movement of the seat, cage and disc in the downstream direction. An annular shoulder in the valve body prevents movement of the seat, cage and disc in the upstream direction. The disc has a hinge pin which is cradled in hinge pin supports of the cage to hold the disc in place. Removal of the bonnet allows access to the valve chamber for replacement of the seat, cage, disc or pin fasteners.
