3.4 MOUNTING THE ACTUATOR ONTO THE
VALVE
Lubricate the valve stem.
Thoroughly clean the coupling surfaces of the
valve and actuator flanges, degreasing them
carefully since torque is transmitted by friction.
Lift the actuator with slings suitable for its
weight.
The actuator will operate satisfactorily in any
position. When mounted upside down, the end
of the stem cover tube should be drilled Ø5 mm
to avoid build up of service fluid or rainwater.
3.4.1 Coupling type “A”
Place the actuator vertically on the stem, screw
the threaded bushing of the coupling block on
the valve stem, rotating (normally counter-
clockwise) until the coupling block and flange
surfaces of the valve are securely in contact.
For safety purposes, rotate the handwheel
in the opening direction for about two turns

WARNING
Never lift the valve/actuator assembly without
securing slings to both the valve and the actuator.
YES NO
WARNING
Never use the handwheel to lift the actuator.
3.4.2 Couplings type “B1”, “B2”,”B3” and “B4”
Check the dimensions of the valve mounting
details, paying particular attention to the
protrusions of the valve stem in order to avoid
any axial thrusts to the internal parts of the
actuator or the valve when the screws are
tightened.
Engage the manual operation. Place the
actuator vertically on the valve stem. Carry
out the coupling operations (if necessary with
the help of manual operation); make sure no
mating parts are forced.
3.4.3 Actuator fixing
IMPORTANT
In case the actuator is supplied without stud bolts
and nuts the following materials must be used as
a minimum:
- ISO class 8.8 for studs bolts and nuts
or
- ASTM A 320 Grade L7 (or L7M) for studs bolts
- ASTM A 194 Grade 4 for nuts
Model Tightening torque (Nm)
in order to lift the valve gate from its seat to
avoid (during bolt fixing) excessive axial thrusts
on the internal parts of the valve and of the
actuator.
Depending on the conditions of assembly, it
could be easier to separate the thrust block
from the actuator and mount it onto the
valve yoke.
