to properly centre the seal [7].

ASSEMBLING THE VALVE AND THE OPERATING SYSTEM:

guidelines should be followed for the automatic system:
Do not forget to fit the position pointer [45] and in particular to check the N.C or N.O valve
operating position (position of drive squares).
Before making the final network connections, check that the valve is operating normally.
If you encounter problems when carrying out the operations described below, do not
hesitate to contact us.

We also remain at your disposal to maintain your valves either on-site or at our
own premises.
