C 5012 Oxygen Valve Maintenance; Replacing The C 5010 Sealing Ring - IKA C 5010 Betriebsanleitung

In order to replace the O-ring the
valve inside the cover has to be
opened:
• Unscrew locking screw (item 15) using a
slotted screwdriver.
• Remove valve piston (item 16) and O-ring
(item 17).
• Replace O-ring (cf. O-ring set).
• Insert piston in such a way that the guide
pin point toward the locking screw.
• Tighten locking screw.

Disassembly of the oxygen valve for the and C 5012 decomposition
vessel is identical to the procedure for the C 5010 decomposition vessel.
However, the components differ in their design.
Pos. 3 valve piston
Pos. 4 pressure spring
Pos. 5 locking screw
Pos. 20 O-Ring
Assembly of the components shall be
performed as specified in the preceding
diagram.
The pressure spring (item 4) does thus the
oxygen valve the decomposition vessel is
self-sealing.
In order to raise the sealing ring (item 13) the circlip (item 11) has to fi rst
be pried out of the groove in the cover.
This is performed using a medium-sized slotted screwdriver, the fl at
side of which is pressed between the circlip and the cover. When the
screwdriver is properly positioned the circlip is removed by pushing back
the cover edge.
Now the compression ring (item 12) and the sealing ring (item 13) may
16 be lifted.

Pos. 11 circlip
Pos. 12 compression ring
Pos. 13 sealing ring
When joining the individual parts make certain that the chamfers of the
compression ring and sealing ring point toward the side of the cover (see
diagram).
Mounted components:
The circlip (item 11) has to
snap exactly into the cover
groove. There is hardly any
play between the circlip and
the compression ring after
assembly.
The circlip may not be put
into the upper groove of the
cover groove because the
decomposition vessel would
not be tight.
