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.
Step 1
We recommend to use some water to "lubricate" on the bonnets
round edge, before mounting the diaphragm. This makes it much
easier to mount diaphragm correctly.

Step 2
Mount the disc in the bonnet, with the plane disc side towards the
bonnet bushing. It is important that the rounded face of the disc
point towards the diaphragm.

Step 3
Fit diaphragm to the bonnet. Press only with the fingers so no
scratch comes on the diaphragm as this might result in leakage.
Be sure that the diaphragm is fitted correctly on the "round edge"
on the bonnet.
