IQ3 manual – Section: Mounting the Actuator 5
WARNING: The thrust
compensator assembly and
actuator should be fully supported
until full valve shaft engagement
is achieved and the assembly is
secured onto the valve flange.
A suitable mounting flange conforming
to ISO 5210 or USA Standard MSS
SP101 must be fitted to the valve.
Actuator to valve fixing must conform
to Material Specification ISO Class 8.8,
yield strength 628 N/mm
2
.
WARNING: Do not lift the
actuator and the valve combination
via the actuator. Always lift the
valve/actuator assembly via the
valve. Each assembly must be
assessed on an individual basis for
lifting.

3. Mounting the Actuator
WARNING: Refer to the Weights
and Measures section in this manual
to ensure correct lifting practices are
followed.
Ensure that the valve is secure before
fitting the actuator as the combination
may be top heavy and therefore
unstable.
If it is necessary to lift the actuator
using mechanical lifting equipment,
certified slings should be attached
as indicated in Fig 3.1. The thrust
compensator assembly may also require
lifting equipment, certified slings
should be attached to a minimum of 4
of the fixing holes with equal spacing
to ensure a stable, balanced lift.
At all times, trained and experienced
personnel should ensure safe lifting
particularly when mounting actuators.
