Section 2: Installation
Installation
2.3
Storage
If the actuator needs storage before installation, follow these steps:
•
Place it on a wood surface in order not to deteriorate the area of valve coupling.
•
Make sure that plastic plugs are present on the hydraulic and electrical
connections (if present).
•
Check that the cover of the control group and of the limit switch box (if any) are
properly closed.
If the storage is long-term or outdoor:
•
Keep the actuator protected from direct weather conditions.
•
Replace plastic plugs of hydraulic and electrical connections (if any) with metal
plugs that guarantee perfect tightness.
•
Coat the valve coupling area with oil, grease or protection disc.
•
Periodically operate the actuator (Section 3.3).

Actuator Assembly on the Valve
2.4.1
Types of Assembly
The adapter pedestal in fabricated carbon steel is specifically designed for adaptation to
any type of valve with provision for local indicator, limit switches and other accessories
(on request).
Lift the actuator by safety hook for chains using the lifting points (see Section 2.2) on the
top of actuator for handling, transporting and assembling in vertical position (see
Figure 3). For handling, transporting and assembling the actuator in horizontal position
by safety hook for chains, use the lifting points on the top of cylinder head flange and on
coupling flange (see Figure 4).
2.4.2
Assembly Procedure
!
WARNING
Failure to comply with the following procedures may impair product warranty. Installation,
commissioning and maintenance and repair works should be carried out by qualified staff.
A non-conforming assembly could be the source of serious accidents.
For actuator assembly on the valve:
NOTICE
Check that the assembly position, as shown on the documentation, complies with
system’s geometry. Check the consistency of the parts of actuator-valve coupling.
