WARNING
Uncontrolled start-ups!
(only for pneumatic actuator)
There is a risk of injury if pneumatic rotary
actuators create a very high torque during
actuation or by spring force.
•
Secure the rotary actuator against any
unintentional start-up or unexpected
spinning.
•
Work on the pneumatic rotary actua-
tors in a prudent way.
•
In case of single-acting rotary actua-
tors (type GS), make sure that the ro-
tary actuator is in the home position
(relaxed springs) when disassembling.
CAUTION
Hand injuries!
When mounting the rotary actuator on
the valve spindle, the rotary actuator is
pushed to the connection point/flange of
the valve.
When disassembling the rotary actuator
or removing the rotary actuator from the
valve spindle, the parts can slip down.
There is danger of crushing the hands!
•
Carefully pull off the rotary actuator.
•
Keep fingers and hands away from
the connection point.
PZDS/EZDS-IM-DE-B-EN-01-23 Rev.0
NOTE
Material damage to valve spindle!
Material damage can occur if you use
built-on rotary actuators as levers.
•
Do not use built-on actuators as le-
vers as they could damage the actua-
tor and the valve.
