5.0 DISASSEMBLY
(Continued)
5.1.2.4 Disc/Hinge Assembly (Fig. 16)
The disc (004) in all Anchor/Darling swing check valves is attached to the hinge by means of
a disc in (an integral part of the disc) which is inserted into a hole in the lower portion of the
hinge. It is held in place by a disc nut (239 or 4B) and a disc washer (250 or 4A) threaded on
the disc pin. The nut is locked by either a lock wire or a disc nut pin (265 or 4C). The disc can
be removed from the hinge by removing the disc nut pin, the disc nut and the disc washer, in
that order. The disc can then be separated from the hinge.
