12.1 Valve disassembly
(removing actuator
from body)
5. Move actuator A to the open position.
6. Remove actuator A from valve body 1.
7. Move actuator A to the closed position.
Important:
After disassembly, clean all parts
of contamination (do not damage
parts). Check parts for potential
damage, replace if necessary (only
use genuine parts from GEMÜ).
12.2

Removing the diaphragm

Important:
Before removing the diaphragm,
please remove the actuator, see
chapter 12.1 "Valve disassembly
(removing actuator from body)".
1. Unscrew the diaphragm.
2. Clean all parts of the remains of product
and contamination. Do not scratch or
damage parts during cleaning!
3. Check all parts for potential damage.
4. Replace damaged parts (only use
genuine parts from GEMÜ).
12.3

Mounting the diaphragm

12.3.1 General information

Important:
Mount the correct diaphragm
that suits the valve (suitable for
medium, medium concentration,
A
temperature and pressure). The
diaphragm is a wearing part. Check
2
the technical condition and function
of the valve before commissioning
and during the whole term of use.
Carry out checks regularly and
determine the check intervals in
accordance with the conditions of
use and / or the regulatory codes
1
and provisions applicable for this
application.
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.
