General safety instructions



The control valve must be mounted, started up and serviced by fully trained

and qualified personnel only. Make sure employees or third persons are not

exposed to any danger.



All safety instructions and warnings in these instructions, particularly those

concerning installation, start-up and maintenance, must be strictly observed.



The control valve fulfills the requirements of the European Pressure Equipment

Directive 97/23/EC. Valves with a CE marking have a declaration of con -

formity that includes information on the applied conformity assessment proce -

dure. The declaration of conformity can be viewed and downloaded on the In -

ternet at http://www.samson.de.



For appropriate operation, make sure that the control valve is only used in ap -

plications where the operating pressure and temperatures do not exceed the

operating values based on the valve sizing data submitted in the order.

Note that the manufacturer does not assume any responsibility for damage

caused by external forces or any other external influences.

Any hazards which could be caused in the control valve by the process me -

dium, operating pressure, control signal or moving parts are to be prevented

by means of appropriate measures.



Proper shipping and appropriate storage are assumed.

Caution



For installation and maintenance work on the control valve, make sure the

relevant section of the plant is depressurized and, depending on the process

medium used, drained as well. Depending on the application, cool down or

heat the valve to ambient temperature prior to starting any work on the valve.



When working on the valve, make sure that the supply lines for the air supply

as well as the control signals are disconnected or locked to prevent any ha -

zards that could be caused by moving valve parts.



Special care is needed when the actuator springs of a pneumatic control valve

are pretensioned. These actuators are labeled correspondingly and can also

be identified by three long bolts at the bottom of the actuator. Prior to starting

any work on the valve, you must relieve the compression from these preten -

sioned springs.
