Unpacking & Handling
SPI units are packed in a variety of configurations depending upon the application, size of the actuating
gearbox mounted to and the quantity of the consignment. Therefore it is the responsibility of the individual
unpacking and handling the unit to carry out a risk assessment for the particular consignment and to unpack
and handle accordingly using safe working practices. The packaging should be re-used or recycled according
to local regulations. The packaging materials used are wood, cardboard, paper, steel and polyethylene. SPI
units should be lifted using soft slings (where required) and care should be taken not to apply any shock
loads. The individual risk assessment should identify which part of the SPI and or actuating gearbox should
be used for lifting. Once the SPI or actuating gearbox combination is fitted to the valve, the assembled valve,
gearbox and / or SPI must not be slung from the gearbox or SPI unit.
⚠
WARNINGS
⚠
⚠
Individual weights for actuating gearboxes and SPI units are recorded on their respective nameplates;
actuating gearboxes and SPI units may present an unbalanced load.
⚠
Only trained and experienced personnel should carry out handling. At all times, safe handling must be
ensured.
⚠
Each assembly must be assessed to identify all risks associated with handling.
⚠
The actuating gearboxes and SPI units must be fully supported until full valve shaft/stem engagement
is achieved and the actuating gearbox or SPI is secured to the valve flange.
⚠
Once connected to the valve, each assembly must be assessed on an individual basis for safe handling /
lifting. Never lift the complete combination-valve assembly via the actuating gearbox or SPI.

Installation
Should the SPI be pre-mounted to the input flange of an actuating gearbox, please see the relevant
installation, operating and maintenance manual for the actuating gearbox for instructions on how to
assemble the gearbox to the valve, and continue to section 7
–
Should the SPI be retrofitted to an existing actuating gearbox in the field, please follow the instructions
below for SPI installation to a valve for a non-thrust taking application, treating the actuating gearbox input
shaft as the valve shaft.
⚠
WARNINGS
⚠
⚠
Once fully torque-tightened, none of the fasteners in the SPI unit should be re-used. All fasteners with
the exception of the position indicator plate fasteners (D), electrical cover fasteners (E) and internal cam
and cam disc fasteners (H and I) are torque-tightened at the factory. If a fastener is loosened for any
reason, then it should be discarded and a new fastener used in its place.
⚠
The SPI must not be used to carry the combined weight of the actuating gearbox and valve during
lifting operations.
Visually check the SPI for signs of damage during transit or storage. Contact Rotork for advice if more serious
damage is observed.
