2.1 CHECKS UPON ACTUATOR RECEIPT
❑
Check that the model, the serial number of the actuator and the
technical data reported on the identification plate correspond with
those of order confirmation (Sect. 1.2).
❑
Check that the actuator is equipped with the fittings as provided for
by order confirmation.
❑
Check that the actuator was not damaged during transportation: if
necessary renovate the painting according to the specification
reported on the order confirmation.
❑
If the actuator is received already assembled with the valve, its
settings have already been made at the factory.
If the actuator is delivered separately from the valve, it is
necessary to check, and, if required, to adjust, the settings of the
mechanical stops (Sect. 3.4) and of micro-switches (if any) (Sect.
3.5).
2.2 ACTUATOR HANDLING
The lifting and handling should be made by qualified staff
and in compliance with the laws and provisions in force.
The fastening points are appropriate for the lifting of the
actuator alone and not for the valve + actuator assembly.
Avoid that during the handling, the actuator passes above
the staff.
The actuator should be handled with appropriate lifting
means. The weight of the actuator is reported on the
delivery bill.
