Disassembly Instructions for AKH6
For all jobs which are to be carried out on an installed valve, the works safety require-
ments and the gerneral accident prevention instructions must be observed. Moreover,
the general installation and maintenance instructions for atomac fluorcarbon resin lined
valves must be considered.
1.
Prior to disassembly, the valve must be cleared of all fluid according to the
above-mentioned instructions. Particular care must be taken that during rin
sing and draining of the piping, the valve is opened and closed repeatedly.
These cycles (opening and closing) are to be
repeated during draining of the piping. Only when following this procedure, is it
ensured that all remaining pressure inside the body (stem guide and ball seats) is
eliminated.
2.
For disassembly of the valve, put body on a work bench with a soft cover (rubber
A
mat). If necessary, remove the stops (310). Remove hexagon bolt (110)
and lock washer (150) and grounding device
