WARNING
!
Crush hazard arising from moving parts.
The actuator contains moving parts (actuator stem), which can injure hands or fingers if
inserted into the actuator.
Î
Do not insert hands or fingers into the yoke while the valve is in operation.
Î
While working on the actuator, disconnect and lock the pneumatic air supply as well
as the control signal.
Risk of personal injury when the actuator vents.
While the valve is operating, the actuator may vent during closed-loop control or when
the valve opens or closes.
Î
Install the control valve in such a way that the actuator does not vent at eye level.
Î
Use suitable silencers and vent plugs.
Î
Wear eye protection when working in close proximity to the control valve.
Risk of personal injury due to preloaded springs.
Actuators with preloaded springs are under tension. They can be identified by the long
bolts protruding from the top and bottom diaphragm cases.
Î
Before starting any work on the actuator, relieve the compression from the preload -
ed springs (see section 9.3).
