8.4. DISASSEMBLY AND ASSEMBLY THE VALVE
Proceed with caution. Personal injury can occur.
Always disconnect the compressed air before starting to disassemble the valve.
Never disassemble the valve clamps directly without reading the instructions carefully,
since the actuator contains a spring inside it with an applied load.
Valve and actuator assembly and disassembly should only be done by qualified persons.
The following tools are needed in order to disassembly and assembly the valve and the drives:
- two 10 mm crescent spanners
-
appropiate tool (not piercing) to mount the seat seals.
8.4.1. Disassembly
8.4.2. Assembly
1. At the NC valves, apply compressed air to the
actuator (10) to the plug shaft (08) passes to the
open position.
2.
Loosen and separate the clamp (34).
3.
Separate the valve body (01) from the assem
-
bled formed by the actuator (10) - lantern (21)
- plug shaft (08).
4. At the NC valves, release the compressed air
from the actuator (10).
5.
Loosen the lower threaded guide (55A) from
the actuator (10) thus will allow the lantern to turn
freely.
6.
Unscrew the plug shaft (08) from the actuator
(10) shaft with two 10 mm crescent spanners.
One of the crescent spanners will fix the actuator
shaft for the upper part of the actuator and the
other one shall turn the plug shaft (08) to uns
-
crew it.
7.
Remove the body cover (12) from the shaft.
8.
Separate the upper guide bushing (17), the
shaft seal (05) and the O-ring (20B) from the
body cover (12).
9. Unscrew and remove the lower threaded gui-
de (55A) from the actuator (10).
10.
Separate the lantern (21).
11.
Remove the conical seat seal (05C) from the
plug shaft (08) following the instructions in chap

.
12. At the INNOVA Mini K valves, remove the ra-
dial seat seal (05D) following the instructions in
chapter
8.5. Replacing the seat seal
.
1. Lubricate the seals with soapy water or suita-
ble grease to facilitate their assembly.
2.
Mount the conical seat seal (05C) to the plug
shaft (08) following the instructions in chapter
8.5. Replacing the seat seal
.
3. At the INNOVA Mini K valves, assemble the
radial seat seal (05D) to the plug shaft (08) fo
-
llowing the instructions in chapter
8.5. Replacing
the seat seal
.
4.
Mount the seat seal (05) and the O-ring (20B)
to the body cover (12).
5.
Place the guide bushing (17) on the body co
-
ver (12).
6.
Place the body cover (12) on the plug shaft
(08).
7.
Place the lantern (21) on the actuator (10) and
fix it with the lower threaded guide (55A) of the
actuator.
8.
Thread the plug shaft (08) with the actuator
shaft (10).
9. At the NC valves, apply compressed air to
the actuator (10) to the plug shaft (08) passes to
the open position.
10.
Mount the actuator (10) - lantern (21) - plug
shaft (08) assembly on the valve body (01) and
fix it with the clamp (34). The body is steerable
360⁰, place it as the needs of the user.
11. At the NC valves, release the compressed air
from the actuator (10).
12. Open and close the valve several times appl-
ying compressed air to the actuator to make sure
it operates correctly and the shaft seal fits smoo
-
thly with the valve body.
