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 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 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

mat). If necessary, remove the stops (310). Remove hexagon bolt (110)

and lock washer (150) and grounding device

(170).

3. Open valve completely. Remove hand lever

(300).

4. Disassemble gland follower (060) and gland

insert (065). If necessary, stud bolts

(120) can also be removed now.

5. Remove body bolts (080) and separate side

piece from body.

6. Removerstballseatring(030).

7. Put ball in closed position and push ball

out of the body.

8. Remove stem (040) by pushing it down

through the body (010). Care must be taken

not to damage body liner.

9. Chevron packing (100) can easily be

removed.

When bolting together dissimilar materials, always tighten to the lowest recommended torque of

the components in the joint. Using higher torques may cause excessive deformation of the „softer“
