opening, with detection, simple or micrometric adjustment) or DPAX1 AUTOMATIC,
Compact interflange valves.
INTRODUCTION
IMPORTANT: Before carrying out any maintenance work, check with the supervisor that
the installation is stopped and drained (pipes empty and depressurised, pumps stopped,
tanks shut off or empty).
The disassembly process for manual or automatic butterfly
valves is divided into three distinct steps
DISASSEMBLING THE VALVE
Before starting the disassembly procedure, if the valve is fitted with a signalling box it may
be necessary to detach the signalling unit from the actuator.
1.3 DISMANTLING THE SIGNALLING BOX:
Dismantling without disconnection
IMPORTANT: Before starting any work on the box, it is important to ensure
that the air supply is closed and that the circuit is purged.
Dismantling with disconnection
IMPORTANT: Before starting any work on the box, it is important to ensure
that the mains supply is switched off, that the air supply is closed and that the
circuit is purged.
NOTE: To fit and remove the unit, refer to its maintenance notice

1.7 INTRODUCTION:
Our valve components are listed and referenced in the "Parts catalogue" section
of our folder and our CD-ROM, together with the information necessary for ordering
your spare parts.
1.8 REASSEMBLING THE MANUAL AND AUTOMATIC OPERATING SYSTEM:
This procedure is performed in the reverse order to dismantling. However, it is necessary
to take into account the following comments for the automatic system:
Before reassembling the parts, ensure that the assembly is lubricated with an appropriate
lubricant (water-resistant and temperature-resistant food grade grease).
Example for information: PURE TAC LUBRIPLATE by TOTAL FINA)
NOTE: For removing and refitting the actuator, refer to its maintenance notice.
Operate the actuator with air before continuing reassembly.
NOTE !

IT-TDFX-222 Revision 0 Page 10/16 October 2008
1.9 REASSEMBLING THE BUTTERFLY VALVE:
This operation is carried out in the reverse order to disassembly. The following guidelines
should, however, be followed:
Apply a suitable grease to the guides of the butterfly disc [8], the ½ bodies [9] and the
seal [7].
Keep the butterfly disc [7] in a closed position while tightening the ½ bodies in order
to properly centre the seal [7].
1.10 ASSEMBLING THE VALVE AND THE OPERATING SYSTEM:
This operation is also carried out in the reverse order to disassembly. The following
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.
NOTE: We also remain at your disposal to maintain your valves either on-site or at our
own premises.
