Spare Parts
As SPI units are sealed and qualified for life, replacement of parts does not extend this qualified life. If it is
desired that an inspection of the SPI unit be carried out, Rotork can perform the inspection and will, where
required, replace all screws, O-rings, bearings and grease when re-building the SPI unit. Please note that all
records relating to spare parts are to be maintained by the unit owner.
