16.2 Fitting/removing spare parts

16.2.1 Valve disassembly (removing the actuator from the
body)
1. Move the actuator A to the open position.
2. Remove actuator A from valve body 1.
3. Move the actuator A to the closed position.
Important:
▶ Clean all parts of contamination (do not damage the
parts during cleaning) following removal. Check parts for
potential damage; replace if necessary (only use genuine
parts from GEMÜ).

16.2.2 Removing the diaphragm

▶ Before removing the diaphragm, please remove the actu-
ator, see "Valve disassembly (removing the actuator from
the body)".
1. Unscrew the diaphragm.
ð Please note: Depending on the version, the com-
pressor may fall out.
2. Clean all parts of contamination (do not damage parts dur-
ing cleaning).
3. Check parts for potential damage, replace if necessary
(only use genuine parts from GEMÜ).

16.2.3 Mounting the diaphragm

▶ Fit the diaphragms suitable for the product (suitable for
medium, medium concentration, temperature and pres-
sure). The diaphragm is a wearing part. Check the tech-
nical condition and function of the product before com-
missioning and during the whole term of use. Carry out
checks regularly and determine the check intervals in ac-
cordance with the conditions of use and/or the regulatory
codes and provisions applicable for this application.
▶ 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
leakage of the product. If the diaphragm is screwed in too
far, perfect sealing at the valve seat will not be achieved.
The function of the product is no longer ensured.
▶ Incorrectly mounted diaphragms cause the product leak-
age and emission of medium. In this case, remove the
diaphragms, check the complete valve and diaphragms
and reassemble again proceeding as described above.
