REASSEMBLING THE VALVE
This procedure is performed in the reverse order to dismantling. You should follow the
guidelines given below:
• We recommend using a medium thread lock compound to lock the plug during
reassembly on the actuator and retightening the plug of diaphragm valves after first usage with
temperature.
• Do not forget to supply air to the actuator before tightening the clamp collars.
• Before making the final network connections, check that the valve is operating normally. If you
encounter problems when carrying out the operations described above, do not hesitate to
contact us.
• You can also contact us regarding maintenance for your valves either on-site or at our own
premises.
