Important:
If the diaphragm is not screwed
into the adapter far enough, the
closing force is transmitted directly
onto the diaphragm pin and not
via the compressor. This will cause
damage and early failure of the
diaphragm and thus leakage of the
valve. If the diaphragm is screwed
in too far no perfect sealing at the
valve seat will be achieved. The
function of the valve is no longer
ensured.
Important:
Incorrectly mounted diaphragm
may cause valve leakage /
emission of medium. In this case
remove the diaphragm, check the
complete valve and diaphragm and
reassemble again proceeding as
described above.
The compressor is loose.
It contains either a washer (DN 15 / DN 25)
or spring washers (DN 32 / DN 40: 8 pieces -
DN 50: 10 pieces).
Insert spring washers that have fallen out as
shown in the following pictures:
