⚠
Isolation:
The equipment must be isolated / de-energised prior to removal of covers / servicing. Failure
to adhere to this may lead to possibility of fire, serious injury or death.
⚠
Wiring:
Do not replace any wiring with wiring rated to a lesser rating. Ensure that wiring terminals are
correctly integrated into additional wiring circuits with respect to local wiring regulation. The risk associated
with connection of terminals is placed solely on the installer. Failure to adhere to this may lead to fire,
serious injury or death.
⚠

The user must ensure that the operating environment and any materials surrounding the SPI cannot lead to
a reduction in the safe use of, or the protection afforded by, the product. Where appropriate the user must
ensure the product is suitably protected against its operating environment.
⚠
Operating Speed:
The SPI unit is not designed to be operated by anything other than a hand wheel, as
such it must not be operated by any high speed device such as a drill, etc.

Specific Conditions of Use for Hazardous Area Approved Units
1.
This equipment incorporates an anodized outer surface. To avoid the possibility of electrostatic
charges, cleaning must only be carried out with a damp cloth.
2.
The SPI product is only for use in manual applications.
3.
In cases where two intrinsically safe proximity sensors are installed the associated circuits are to be
considered as separate intrinsically safe circuits, the stated input parameters being applied to each
circuit separately.

Specifications and Intended Use
3.1
Scope of Use
Rotork SPI units are valve position indicators. They are designed to be mounted to an actuating gearbox, or
directly mounted to smaller valves for either non-thrust taking, or with the addition of a thrust base
assembly, thrust taking applications.
The unit is designed to mechanically indicate valve position locally, and electrically signal open / close
position of the valve to a remote location, as well as transmit the required operating torque to the valve
actuating gearbox or valve via an input shaft mounted handwheel.
Rotork products should not be modified in any way nor should any parts be removed without first consulting
Rotork. For applications outside of this scope, please contact Rotork. The user alone is responsible for the
appropriate use of the SPI in consideration of the basic conditions existing at the plant.
When using this document, also refer to the contract specific general arrangement drawing.
