parts kit
1. Remove actuator A (see chapter 5.1
"Disassembly of actuator from valve
body").
2. Disassemble the actuator top (see chapter
5.2 "Disassembly of actuator top").
3. Remove compression spring 17 from
actuator base 25.
4. Remove O-ring 24 from piston sleeve 13
(only with actuator size 2).
5. Pull piston sleeve 13 out of actuator top 10.
6. Remove O-ring 44 from actuator top 10
(only with actuator size 1).
7. Remove lip ring 21 from piston 20.
8. Remove O-ring 22 from piston 20.
9. Pull spindle 2 downwards in the direction
of union nut a and completely out of
actuator base 25.
10. Remove circlip 3 in actuator base 25
using an appropriate tool.
11. Pull out guide bush 5, compression
spring 6, pressure ring 9, chevron
packings 8 and 33 and support ring 7 from
the pipe in actuator base 25, in the order
listed here.
12. Lubricate new chevron packings using
appropriate lubricant* prior to installation.
* GEMÜ recommends the lubricant
"Dowcorning 111 Molycote".
13. Insert the new gland packing into the
pipe in the actuator base 25 in the
following order:
1. Support ring 7
2. Chevron packings 8 and 33
Arrange the sharp-edged
sides of chevron packings 8
and 33 in the direction
of the valve body, as it
will otherwise not be
possible to achieve sealing
tightness.
Layout of chevron packings:
• PTFE (not included with
actuator size 2)
• Elastomer
• PTFE
• Elastomer
• PTFE
3. Pressure ring 9
4. Compression spring 6
5. Guide bush 5
14. Lock the gland packing in place using
the circlip 3.
15. Push spindle 2 through actuator base 25
and back into its initial position.
16. Insert new O-ring 22 into piston 20.
17. Assemble new lip ring 21 on piston 20.
18. Insert new O-ring 44 in actuator top 10
(only with actuator size 1).
19. Lubricate new piston sleeve 13 using
appropriate lubricant* and push it into
actuator top 10 (pay attention to the
installation position).
* GEMÜ recommends the lubricant
"Dowcorning 111 Molycote".
20. Insert new O-ring 24 into piston
sleeve 13 (only with actuator size 2).
21. Insert compression spring 17 into
actuator base 25 and centre it.
22. Mount actuator top 10 (see chapter 7.1
"Installation of actuator top").
23. Loosen the retaining nut 19 on the
spindle 2 (hold the spindle 2 in place
using an appropriate tool that will not
damage the spindle surface).
24. Remove retaining nut 19 and seat 14.
25. Clean all parts, do not scratch or
damage the parts during cleaning.
26. Insert new seat 14 into valve plug 15.
27. Apply appropriate thread locking
compound on the thread of valve
plug 15.
28. Position retaining nut 19 on spindle 2
(hold spindle 2 in place using an
appropriate tool that will not damage the
spindle surface) and tighten it.
29. Insert new gasket 4 in valve body 1.
30. Mount actuator A (see chapter 7.2
"Actuator mounting on the valve body").
