For actuator assembly on the valve:
Check that the assembly position, as shown on the
documentation, complies with system’s geometry.
Check the consistency of the parts of actuator-valve
coupling.
A) TO ASSEMBLE THE ACTUATOR ONTO THE VALVE BY BRACKET
WITH THREADED JOINT PROCEED AS FOLLOWS:
1) Check that the coupling dimensions of the valve flange and stem,
or of the relevant extension, meet the actuator coupling
dimensions (valve stem and flange). Lubricate the valve stem with
grease in order to make the assembly easier.
2)
Connect a sling to the support point of the actuator and lift it.
To make easier the assembly , the valve stem has to be in perfect
vertical
position.
Note
:
the eyebolt is sized for the lifting of the only actuator (NOT
AVALVE). Proper lifting points have to be foreseen for
the valve.
