Design and principle of operation
3.3 Accessories
The pneumatic actuator has a female thread
on the base to allow an eyebolt to be
screwed into it. The eyebolt can be used to
vertically lift the actuator and is included in
the scope of delivery. A swivel hoist with
suitable lifting capacity can be retrofitted by
the customer in place the eyebolt. In contrast
to the eyebolt, the swivel hoist may be used
for setting a control valve assembly upright.
However, the eyebolt and the swivel hoist
must not be used to vertically lift the entire
control valve assembly (see the 'Shipment
and on-site transport' section).
3.4 Technical data
