5 Maintenance
Service the valve regularly.
Study the instructions carefully and pay special attention to the warnings!
Always use Alfa Laval genuine spare parts. Always keep spare rubber seals, lip seals and diaphagms in stock.
Check the valve for smooth operation after servicing.

1. Part B
“Part B” has a small and a large diameter as the tool can be
used for two plug sizes – e.g. plug tool = 9614060003 can be
used for ISO51 (small) and ISO63 (large).
“Part B” therefore has to be turned so it matches the plug
size diameter.
2. Part A
“Part A” has an upper and lower exhaust hole, as the tool can
be used for two plug sizes – e.g. plug tool = 9614060003.
The upper exhaust hole is for the small plug size e.g. ISO51
(small) and the lower exhaust hole is for ISO63 (large).
When using a “change-over plug” the spindle must also be
fitted in “part A” and “part B” (see drawing 2).
When using a “standard shut-off plug” the spindle is only fitted
in “part B” (see drawing 1).
3. Fit the plug spindle in “part B” or “part A”.
Place “part A” onto “part B” and then press “hard” down on
top of “part A”.
Now fit the screwdriver into the exhaust hole and underneath
the plug groove meanwhile keeping the pressure on “part A”.
This should ensure correct removal of air behind the seal
ring. Normally the sound “Psst” can be heard one time (see
drawing 3).
A “drill press” can of course also be used to press down on
“part A”.
4. It is important to release compressed air behind the seal ring.
This is done with a screwdriver and always underneath the
plug as shown (see drawing 4).
