1.3 Notes on possible property damage

NOTICE
!
Risk of valve damage due to contamination (e.g. solid particles) in the pipeline.
The plant operator is responsible for cleaning the pipelines in the plant.
Î Flush the pipelines before start-up.
Î Observe the maximum permissible pressure for valve and plant.
Risk of valve damage due to unsuitable medium properties.
The valve is designed for process media with defined properties.
Î Only use process media specified for sizing the valve.
Risk of damage to the electric actuator due to the supply voltage exceeding the per-
missible tolerances.
The Types 5824, 5827 and 5825 Electric Actuators are designed for use according to
regulations for low-voltage installations.
Î Observe the permissible tolerances of the supply voltage.
Risk of damage to the actuator and control thermostat due to excessively high tight-
ening torques.
Observe the specified torques when tightening the Type 2430 Control Thermostat and
the Type 5824, 5827 or 5825 Electric Actuator. Excessive tightening torques lead to
parts wearing out more quickly.
Î Observe the specified tightening torques (see section 9.2).
Risk of damage to the electric actuator due to incorrect connection of the voltage.
The electric actuator has terminals to retract the stem (eL terminal) and to extend the
stem (aL terminal).
Î Do not apply a voltage to eL and aL at the same time.
Risk of damage to the electric actuator by moving the actuator stem too far.
The actuator stem of the electric actuator can be adjusted manually.
Î Only retract the actuator stem as far as the end position at the maximum.
