5.0 DISASSEMBLY
(Continued)
5.1.2.1.1 Pipe Plug Seal Cover (Fig 10 & 11)
In this design the cover (5A) is removed by unthreading the plug out of the body. In
some smaller valves, the plug may be an integral part of hinge pin (5) and its
removal will as well withdraw the pin. In larger valves, the plug is a separate part
and can be removed by itself. Where a separate plug is provided, a roll pin (58),
inserted into the ends of both the plug and the hinge pin, serves to prevent hinge pin
rotation. Care must be taken during disassembly not to misplace it.
