For all jobs which are to be carried out on an installed valve, the works safety requirements and the general accident prevention instructions must be observed. Moreover,
the general installation and maintenance instructions for atomac uorcarbon resin lined
valves must be considered.
1. Prior to disassembly, the valve must be cleared of all uid according to the above-
mentioned instructions. Particular care must be taken that during rinsing 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
mat). Remove hexagon bolt (110) and serrated lock washer (150).
3. Open valve completely. Remove hand lever (070).
4. Disassemble grounding device (170).
5. Disassemble gland follower (060) and gland insert (065). If necessary, stud bolts
(120) can also be removed now.
6. Remove body bolts (080) and separate side piece from body.
7. Remove rst ball seat ring (030).
8. Put ball in closed position and push ball out of the body.
9. Remove stem (040) by pushing it down through
the body (010). Care must be taken not to
damage body liner.
10. Chevron packing (100) can easily be removed.
11. If necessary, remove hand lever stop
(210) by releasing bolt (220).
