General safety instructions
1 General safety instructions
− The control valve must be mounted, started up, or serviced by fully trained
and qualied personnel only; the accepted industry codes and practices
are to be observed. Make sure employees or third persons are not ex-
posed to any danger. All safety instructions and warnings given in these
mounting and operating instructions, particularly those concerning installa-
tion, start-up and maintenance, must be strictly observed.
− The control valves comply with the requirements of the European Pressure
Equipment Directive 2014/68/EU. Valves with a CE marking have a
declaration of conformity which includes information about the applied
conformity assessment procedure.
The declaration of conformity can be viewed and downloaded at

− To ensure appropriate use, only use the valve in applications where the op-
erating pressure and temperatures do not exceed the specications used
for sizing the valve at the ordering stage. The manufacturer does not as-
sume any responsibility for damage caused by external forces or any other
external factors.
− Any hazards that could be caused in the valve by the process medium, the
operating pressure, the signal pressure or by moving parts are to be pre-
vented by taking appropriate precautions.
− Proper shipping and storage are assumed.
− For installation and maintenance, make sure the relevant section of the
pipeline is depressurized and, depending on the process medium, drained
as well. Depending on the eld of application, allow the valve to cool
down or heat up to reach ambient temperature before starting any work
on it.
− When working on the valve, make sure that the pneumatic air supply as
well as the control signal are disconnected to prevent any hazards caused
by moving parts.
− Be particularly careful if the actuator springs are preloaded. Such actua-
tors are labeled correspondingly and can also be identied by three long
bolts protruding from the bottom of the actuator. Before starting any work
on the valve, relieve the compression from the preloaded springs.
