2.1
Checks to be Carried Out on Receiving the Actuator
1.
If the actuator arrives already assembled onto the valve, the settings of the
mechanical stops and of the microswitches (if existing) has already been made
by the person who assembled the actuator onto the valve. If the actuator arrives
separately from the valve, the settings of the mechanical stops and of the
microswitches (if existing) must be checked and, if necessary, carried out while
assembling the actuator onto the valve.
2.
Check that the actuator has not been damaged during transport. If necessary,
repair all damages to the paint-coat, etc.
3.
Check that the model, the serial number of the actuator and the performance
data written on the data-plate are in accordance with those described on the order
acknowledgement, test certificate and delivery note.
4.
Check that the fitted accessories comply with those listed in the order
acknowledgement and the delivery note.
2.2
Storage
(For handling and lifting procedure, please refer to following Figures 6, 7 and 8).
The actuators leave the factory in excellent working conditions and with an excellent
finish (these conditions are guaranteed by an individual inspection certificate); in order to
maintain these characteristics until the actuator is installed on the plant, it is necessary to
observe a few rules and take appropriate measures during the storage period.
1.
Make sure that plugs are fitted in the air connections and in the cable entries. The
plastic plugs, which close the inlets, do not have a weatherproof function, but are
only a means of protection against the entry of foreign matter during transport.
If long-term storage is necessary and especially if the storage is outdoors, metal
plugs must replace the plastic protection plugs, which guarantee a complete
weatherproof protection.
2.
If the actuators are supplied separately from the valves, they must be placed onto
a wooden pallet so as not to damage the coupling flange to the valve. In case of
long-term storage, the coupling parts (flange, drive sleeve, insert bush) must
be coated with protective oil or grease. If possible, blank off the flange by a
protection disk.
3.
In case of long-term storage, it is advisable to keep the actuators in a dry place
or to provide at least some means of weather protection. If possible, it is also
advisable, to periodically operate the actuator with filtered, dehydrated and
lubricated air; after such operations all the threaded connections of the actuator
and the valves of the control panel (if existing) should be carefully plugged.
