General safety instructions
4
The differential pressure regulator must be installed, started up and serviced
only by skilled or semi-skilled staff in accordance with good engineering
practice so that employees and third persons are not exposed to danger.
All safety instructions and warnings given in these mounting and operating
instructions, particularly those concerning installation, start-up, and
maintenance, must be strictly observed.
4
The regulator complies with the requirements of the European Pressure
Equipment Directive 97/23/EC. The declaration of conformity issued for a
valve bearing the CE marking includes information on the applied
conformity assessment procedure and will be provided on request.
4
To ensure appropriate use, only use the regulator in applications where the
operating pressure and temperatures do not exceed the operating values
specified in the order.
Note that the manufacturer does not assume any responsibility for damage
caused by external forces or any other external factors.
Take appropriate safety precautions to prevent hazards that may be caused
in the regulator by the process medium, operating pressure, or moving parts.
4
Make sure the regulator is shipped and stored properly.
Note!
4
Depending on the field of application, allow the regulator to cool down or
warm up to reach ambient temperature prior to starting any work.
Always depressurize the relevant section of the plant and, if necessary, also
drain the pipeline prior to removing the regulator from the pipeline.
4
When controlling freezing media, protect the regulator against frost.
Note!
Non-electric control valves, whose valve bodies are not lined with an
insulating material coating
, do not have their own potential ignition source
according to the ignition risk assessment stipulated in EN 13463-1: 2001,
section 5.2, even in the rare incident of an operating fault. Therefore, such
valve versions
do not
fall within the scope of Directive 94/9/EC.
