Note
− The actuator must be removed first before
mounting the handwheel if the valve and
actuator have already been assembled.
See instructions on how to remove the ac-
tuator in the associated actuator documen-
tation.
− In case, the valve, actuator, and hand-
wheel are delivered separately, assemble
components as described in following.
− See associated valve and actuator docu-
mentation for additional mounting instruc-
tions.
NOTICE
!
Risk of damage to control valve components
due to excessively high or low tightening
torques.
Observe the specified torques on tightening
control valve components. Excessively tight-
ened torques lead to parts wearing out
quicker. Parts that are not tightened far
enough may loosen.
Observe the specified tightening torques
(u AB 0100).
NOTICE
!
Risk of damage to control valve components
due to the use of unsuitable tools.
Certain tools are required to work on the
control valve.
Only use tools approved by SAMSON
(u AB 0100).

NOTICE
!
Risk of damage to control valve components
due to the use of unsuitable lubricants.
The lubricants to be used depend on the ma-
terial of the control valve. Unsuitable lubri-
cants may corrode and damage the valve
surface.
Only use lubricants approved by SAMSON
(u AB 0100).
NOTICE
!
Risk of malfunction due to different travels.
Make sure that the travels of the actuator,
handwheel, and valve match. If necessary,
contact SAMSON's After-sales Service de-
partment.
NOTICE
!
Risk of control valve damage due to the in-
correct mounting.
Versions with anti-rotation fixture at the plug
stem must only be mounted by SAMSON's
After-sales Service department or after they
have given their consent.
